give an example of the difference between augmented feedback and inherent feedback in driving a car with a manual transmission.

Answers

An example of augmented feedback would be a beep or a light that informs the driver when they need to shift gears. In contrast, inherent feedback is the sensory information that the driver receives through the car's clutch, gear shifter, and engine sound, which allows them to feel the speed and the gear changes.

Augmented feedback is information that is provided to the driver by an external source. For example, a driving instructor telling a student driver to shift gears at a certain speed. Inherent feedback, on the other hand, is feedback that is naturally perceived by the driver. In the case of driving a manual transmission car, inherent feedback would be the sound and feel of the engine, which the driver uses to determine when to shift gears.

Calculate the pressure coefficients on the surfaces of the symmetrical airfoil in the figure and the pitch coefficient around the quarter chord point within the framework of linearized potential theory.

Calculate the pressure coefficients on the surfaces of the symmetrical airfoil in the figure and the

Answers

To calculate the pressure coefficients on the surfaces of the symmetrical airfoil, we can use the concept of linearized potential theory. This theory assumes that the flow is irrotational, inviscid, and incompressible.

Step 1: Determine the freestream conditions
Start by identifying the freestream conditions, such as the velocity of the flow (V∞) and the density (ρ) of the fluid. These values are usually provided in the problem statement.
Step 2: Calculate the dynamic pressure
The dynamic pressure (q) is given by the formula:
q = 0.5 * ρ * V∞^2
Step 3: Determine the pressure at various locations on the airfoil
Using Bernoulli's equation, we can relate the pressure at different locations on the airfoil to the freestream conditions. Bernoulli's equation is given by:
P + 0.5 * ρ * V^2 = constant
At the freestream condition, the pressure coefficient (Cp) is defined as:
Cp = (P - P∞) / q
where P is the pressure at a given location on the airfoil and P∞ is the freestream pressure.
Step 4: Calculate the pressure coefficients on the airfoil surfaces
Using the pressure coefficient formula, calculate the pressure coefficients at different points on the upper and lower surfaces of the airfoil.

Typically, these points are defined using the x-coordinate or the distance from the leading edge of the airfoil. The pressure coefficient is negative on the upper surface and positive on the lower surface.
Step 5: Calculate the pitch coefficient around the quarter chord point
The pitch coefficient (Cm) around the quarter chord point is given by:
Cm = (Cp upper surface + Cp lower surface) / 2
where Cp upper surface and Cp lower surface are the pressure coefficients on the upper and lower surfaces, respectively.
By following these steps, you should be able to calculate the pressure coefficients on the surfaces of the symmetrical airfoil and the pitch coefficient around the quarter chord point within the framework of linearized potential theory.

A soda lime glass sphere of diameter D1 = 25 mm is encased in a bakelite spherical shell of thickness L = 10 mm.The composite sphere is initially at a uniform temperature, Ti = 40°C, and is exposed to a fluid at T[infinity] = 10°C with h= 30 W/m2 · K. Determine the center temperature of the glass at t = 200 s. Neglect the thermal contact resistance atthe interface between the two materials

Answers

Answer:

33.1144 °C

Explanation:

From the information given;

The first step is to find the mean temperature \(T_m\) by using the formula:

\(T_m = \dfrac{T_i- T_\infty}{2}\)

where:

\(T_i\) = initial temperature = 40 °C

\(T_{\infty}\) = ambient temperature = 10 °C

\(T_m = \dfrac{(40+10)^0C}{2}\)

\(T_m = \dfrac{50^0C}{2}\)

\(T_m\)  = 25 °C

\(T_m\)  = (25 + 273) K

\(T_m\)  = 298 K ≅ 300 K

The following properties expressed below were obtained from the thermal physical properties table.

For soda-lime glass at the temperature of 300 K:

Density \(\rho_s = 2500 \ kg/m^3\)

Thermal conductivity \(k_s\) = 1.4 W/m.K

Specific heat \((c_p)_s\) = 750  J/kg.K

For bakelite at the temperature of 300 K:

Density \(\rho_B = 1300 \ kg/m^3\)

Thermal conductivity \(k_B\) = 1.4 W/m.K

Specific heat \((c_p)_B\) = 1465  J/kg.K

From these data; The next process is to find out the thermal diffusivity of each component.

To start with soda-lime glass by using the expression:

\(\alpha_s = \dfrac{k_s}{\rho_s ( c_p)_s}\)

\(\alpha_s = \dfrac{1.4 \ W/m.K}{2500 \ kg/m^3 \times 750 \\J/kg.K}\)

\(\alpha_s = 747 \times 10^{-9} \ m^2/s\)

For Bakelite: The thermal diffusivity is computed as:

\(\alpha_B = \dfrac{k_B}{\rho_B ( c_p)_B}\)

\(\alpha_B = \dfrac{1.4 \ W/m.K}{1300 \ kg/m^3\times 1465 \ J/kg.K}\)

\(\alpha_B = 735 \times 10^{-9} \ m^2/s\)

From the above two results, we will realize that \(\alpha _ s \simeq \alpha _B\)

Thus, as obvious as it is; we presume that the uniform thermal diffusivity

\(\alpha = 740 \times 10^{-9} \ m^2/s\)

However, the diameter of the sphere can be estimated by the summation of the diameter of the glass sphere \((D_1)\) with twice the thickness of the sphere (L)

i.e. \(D = D_1 + 2L\)

D = 25 mm + 2 (10 mm)

D = 45 mm

\(D = 45 \ mm ( \dfrac{10^{-3} \ m}{1 \ mm} )\)

D = 45 × 10⁻³ m

The expression for Biot Number can be estimated by using the formula:

\(Bi = \dfrac{hL}{k}= \dfrac{h(D/6)}{k}\)

Given that:

h = 30 W/m².k

D = 45 × 10⁻³ m

k = 1.4 W/m.K

Similarly, to estimate the Fourier No \(F_o\) by using the expression:

\(F_o = \dfrac{\alpha t}{(D/2)^2}\)

\(F_o = \dfrac{740 \times 10^{-9} \ m^2 /s \times 200 \ s}{( \dfrac{45 \times 10^{-3} m}{2})^2}\)

\(F_o = 0.292\)

It is obvious that \(F_o\) is > 0.2, thus, the validity of one term approximation is certain.

Again; the Biot Number is calculated by using the formula:

\(Bi = \dfrac{h(D/2)}{k}\)

\(Bi = \dfrac{30 \ W/m^2.K (\dfrac{45 \times 10^{-3 }\ m}{2}) }{1.4 \ W/m.k}\)

Bi = 0.482

Bi \(\simeq\) 0.5

We obtain the Eigen coefficient \(\xi_1\) as well as the coefficient for a sphere \(C_1\) using the Bi Number:

From one-term approximation of transient 1 heat conduction in the sphere;

\(\dfrac{T - 10^{0 } \C }{40^{0} \ C - 10^0 \ C} = 1.1441 \ exp \ ( -1.1656^2 \times 0.291)\)

\(\dfrac{T - 10^{0 } \C }{30^{0} \ C} = 0.77048\)

\(T - 10^{0 } \C = 30^{0} \ C \times 0.77048\)

\(T - 10^{0 } \C = 23.1144^0 \ C\)

T = (23.1144 + 10) °C

T = 33.1144 °C

Answers

The H screw on a carburetor is used for adjusting the high-speed fuel-air mixture of the engine. This screw is responsible for controlling the amount of fuel and air that enters the engine when it is running at a high speed.

It is important to set this screw correctly in order to ensure optimal engine performance and prevent damage to the engine. The idle mixture is adjusted using a different screw, typically labeled as the L screw. The throttle position of the carburetor is also important to consider when adjusting the engine speed. A carburetor is a device that mixes air and fuel in the proper ratio for combustion in an internal combustion engine. It is used in older gasoline-powered vehicles and small engines such as lawnmowers, chainsaws, and motorcycles. The carburetor works by regulating the flow of air and fuel into the engine. It consists of a series of tubes, valves, and chambers that control the amount of fuel and air that enter the engine. Carburetors have been largely replaced by fuel injection systems, which are more efficient and reliable, but they still have some applications in small engines and vintage vehicles. Carburetors require regular maintenance and tuning to ensure proper engine performance and fuel efficiency.

\(T_1*P_1^{\frac{1-\gamma}{\gamma} }=T_2*P_2^{\frac{1-\gamma}{\gamma} }\)

Whereas:

\(\gamma=\frac{Cp_{air}}{Cv_{air}} =\frac{1.00J/(g\°C)}{0.718J/(g\°C)}=1.40\)

That is why the final temperature is:

\(T_2=T_1(\frac{P_1}{P_2})^{\frac{1-\gamma}{\gamma} }\\\\T_2=298.15K(\frac{101kPa}{1200kPa})^{\frac{1-1.40}{1.40} }\\\\T_2=604.70K=331.55\°C\)

Moreover, for the work done, since the process is adiabatic, no heat is in the equation:

\(Q-W=\Delta U\)

The inflow into T1 is 2 gal/min from T2 and 6 gal/min containing 6lb of salt from a seawater inlet (an outside source). The inflow into T2 is 8 gal/min from T1. The outflow from T2 is 2 + 6 = 8 gal/min to a retaining pond outside. The mixtures are kept uniform by stirring. Find and plot the salt contents x1(t) and x2(t) in T1 and T2 using eigenvalues and eigenvectors

Answers

x1(t) = 50e^(-10/T1-T2)t − 50e^(-2/T2-T1)t + 100

x2(t) = 100e^(-10/T1-T2)t + 50e^(-2/T2-T1)t + 150

The given system of differential equations represents the dynamics of the concentration of salt in both tanks.

dx1/dt = (8/T1+T2)(x2 − x1) + 6/T1

dx2/dt = (2/T2+T1)(x1 − x2) + 150/T2 − 8/T2

We can rewrite it as Ax' = f(x) where x' is the vector (dx1/dt, dx2/dt), x is the vector (x1, x2), A is the matrix and f(x) is the vector of the remaining terms.

A = [−8/T1−T2, 8/T1+T2]

[2/T2+T1, −2/T2−T1]

f(x) = [6/T1, 150/T2 − 8/T2]

Let's find the eigenvalues and eigenvectors of A.

|A − λI| = 0

|−8/T1−T2−λ, 8/T1+T2|

|2/T2+T1, −2/T2−T1−λ| = 0

(−8/T1−T2−λ)(−2/T2−T1−λ) − (8/T1+T2)(2/T2+T1) = 0

Solving this equation we get two eigenvalues, λ1 and λ2. We can then find the corresponding eigenvectors v1 and v2.

Now let's find the eigenvectors.

For λ1 = −10/T1−T2, we get the eigenvector v1 = (1, 2).

For λ2 = −2/T2−T1, we get the eigenvector v2 = (1, −1).

Now we can write the solution in the form x = c1v1e^(λ1t) + c2v2e^(λ2t) + x0, where x0 is the initial condition vector and c1 and c2 are constants determined by the initial condition.

x1(t) = c1e^(-10/T1-T2)t + c2e^(-2/T2-T1)t + 100

x2(t) = 2c1e^(-10/T1-T2)t − c2e^(-2/T2-T1)t + 150

Using the initial conditions, x(0) = (100, 150), we get c1 = 150/3 and c2 = −50/3.

So the solution is:

x1(t) = 50e^(-10/T1-T2)t − 50e^(-2/T2-T1)t + 100

x2(t) = 100e^(-10/T1-T2)t + 50e^(-2/T2-T1)t + 150

To plot x1(t) and x2(t), we need to choose specific values for T1 and T2. For example, if T1 = 5 and T2 = 10, we get:

x1(t) = 50e^(-2t/3) − 50e^(-t/2) + 100

x2(t) = 100e^(-2t/3) + 50e^(-t/2) + 150

We can then plot these functions using a graphing calculator or software.

A 4-pole, 3-phase induction motor operates from a supply whose frequency is 60 Hz. calculate: 1- the speed at which the magnetic field of the stator is rotating. 2- the speed of the rotor when the slip is 0.05. 3- the frequency of the rotor currents when the slip is 0.04. 4- the frequency of the rotor currents at standstill.

Answers

Answer:

The answer is below

Explanation:

1) The synchronous speed of an induction motor is the speed of the magnetic field of the stator. It is given by:

\(n_s=\frac{120f_s}{p}\\ Where\ p\ is \ the \ number\ of\ machine\ pole, f_s\ is\ the\ supply \ frequency\\and\ n_s\ is \ the \ synchronous\ speed(speed \ of\ stator\ magnetic \ field)\\Given: f_s=60\ Hz, p=4. Therefore\\\\n_s=\frac{120*60}{4}=1800\ rpm\)

2) The speed of the rotor is the motor speed. The slip is given by:

\(Slip=\frac{n_s-n_m}{n_s}. \\ n_m\ is\ the \ motor\ speed(rotor\ speed)\\Slip = 0.05, n_s= 1800\ rpm\\ \\0.05=\frac{1800-n_m}{1800}\\\\ 1800-n_m=90\\\\n_m=1800-90=1710\ rpm\)

3) The frequency of the rotor is given as:

\(f_r=slip*f_s\\f_r=0.04*60=2.4\ Hz\)

4) At standstill, the speed of the motor is 0, therefore the slip is 1.

The frequency of the rotor is given as:

\(f_r=slip*f_s\\f_r=1*60=60\ Hz\)

1.The following are weekly salaries (in birr) of employees of a firm: 91 139 126 119 100 87 61 77 90 95 88 112 118 89 116 97 105 95 80 86 108 106 127 93 86 135 148 116 76 69 The data are to be presented in a frequency distribution. a) How many classes can be used? C) What LCL would be used for the be first class? b) What class width should be used? d) prepare the complete frequency distribution’s ) calculate the mean?

Answers

A commonly used rule is to have approximately 5 to 20 classes. For this dataset, we can choose a moderate number of classes, such as 8.

How to explain the information

b) The class width can be calculated by dividing the range of the data by the number of classes. The range is the difference between the highest and lowest values in the dataset.

Range = Highest value - Lowest value

Range = 148 - 61

Range = 87

Class Width = Range / Number of Classes

Class Width = 87 / 8

Class Width ≈ 10.88

Since class widths should be whole numbers, we can round the class width up to 11 for convenience.

c) To find the LCL for the first class, we can start from the lowest value in the dataset and subtract the remainder of its division by the class width.

LCL = Lowest Value - (Lowest Value % Class Width)

LCL = 61 - (61 % 11)

LCL = 61 - 6

LCL = 55

d) Prepare the complete frequency distribution:

Now, we can organize the data into the frequency distribution using the determined class width and LCL. We will count the number of salaries falling within each class interval.

Class Intervals Frequency

55 - 65 1

66 - 76 3

77 - 87 4

88 - 98 4

99 - 109 3

110 - 120 4

121 - 131 4

132 - 142 3

e) Calculate the mean:

To calculate the mean of the dataset, we sum up all the values and divide by the total number of values (30 in this case).

Sum of Salaries = 91 + 139 + 126 + 119 + 100 + 87 + 61 + 77 + 90 + 95 + 88 + 112 + 118 + 89 + 116 + 97 + 105 + 95 + 80 + 86 + 108 + 106 + 127 + 93 + 86 + 135 + 148 + 116 + 76 + 69

Sum of Salaries = 2878

Mean = Sum of Salaries / Total Number of Values

Mean = 2878 / 30

what is the voltage in the secondary winding of the transformer if the primary voltage is 120v and the turns ratio is 6:1

Answers

To calculate the voltage in the secondary winding of the transformer, you would use the turns ratio formula which states that:

Secondary voltage / Primary voltage = Secondary turns / Primary turns

We know that the primary voltage is 120V and the turns ratio is 6:1, which means that for every 6 turns in the secondary winding, there is 1 turn in the primary winding.

Using the turns ratio formula, we can solve for the secondary voltage:

Secondary voltage / 120V = 6 / 1

Secondary voltage = 720V

Therefore, the voltage in the secondary winding of the transformer would be 720V.

One reason to create database policies is to specify the ______ used in database design (how the data is structured).

Answers

Creating policies to specify database data model for consistency and accuracy.

Why create database policies?

One reason to create database policies is to specify the data model used in database design (how the data is structured).

Database policies are a set of guidelines that help organizations manage their data assets effectively. One key aspect of these policies is specifying the data model used in database design.

A data model is a conceptual representation of data that defines the structure, relationships, and constraints of the data. There are various types of data models, including relational, hierarchical, network, and object-oriented. Each type of data model has its own strengths and weaknesses, and choosing the right model for a particular application depends on factors such as the nature of the data, the processing requirements, and the scalability needs.

By creating policies that specify the data model used in database design, organizations can ensure consistency in how data is structured across different applications and systems. This helps to avoid confusion and errors that can arise when different teams use different data models.

The steps involved in creating database policies to specify the data model used in database design typically include:

Analyzing the data requirements: This involves understanding the nature of the data, its relationships, and the processing needs.Evaluating the available data models: This involves comparing the different types of data models to determine which one is best suited for the particular application.Documenting the chosen data model: This involves creating a clear and concise description of the data model, including its structure, relationships, and constraints.Communicating the policy: This involves sharing the policy with relevant stakeholders, including developers, data analysts, and other teams that work with the data.Enforcing the policy: This involves monitoring compliance with the policy and taking corrective action when necessary to ensure that data is structured consistently and accurately.

Determine the critical load if the bottom is fixed and the top is pinned. ewew = 1. 6 ×(10)3ksi×(10)3ksi ,σyσy = 5 ksiksi

Answers

What is a Critical Load?

Critical load Fcr or buckling load is the value of load that causes the phenomenon of change from stable to unstable equilibrium state.

With that beign said, first it is neessary to calculate the moment of inercia about the x-axis:

\(Ix= \frac{db^3}{12}\\ Ix = \frac{2.(4)^3}{12} = 10.667in\)

Then it is necessary to calculate the moment of inercia about the y-axis:

\(Iy = \frac{db^3}{12}\\ Iy = \frac{4.(2)^3}{12} = 2.662in\)

Comparing both moments of inercia it is possible to assume that the minimun moment of inercia is the y-axis, so the minimun moment of inercia is 2662in.

And so, it is possible to calculate the critical load:

\(Pc\gamma = \frac{2046\pi ^2E.I}{L^2} \\Pc\gamma= \frac{2046.\pi ^2.(1,6.10^3.10^3).2662}{(10.12)^2} \\Pc\gamma= 5983,9db\)

Answers

Both tech a and tech b are correct in their approaches to diagnosing a torque converter clutch (TCC) solenoid problem.

Tech a suggests checking for ground and power with a multimeter first, which is a crucial step in determining if the solenoid is receiving the necessary electrical signals to function properly. Tech b suggests checking the resistance of the TCC solenoid through the connector, which is another critical step in diagnosing the problem. If the resistance is out of specifications, it could indicate a problem with either the solenoid itself or the wires leading to it inside the transmission pan. Therefore, both approaches are valuable in determining the root cause of the TCC solenoid problem and should be used in conjunction for a thorough diagnosis.

The `createGrid` function uses the pseudocode provided to create a 50 x 50 grid of nodes. Each node has a `row` and `col` value to track its position in the grid, as well as pointers to its up, down, left, and right neighbors.

The `displayGrid` function uses nested loops to iterate through each row and column of the grid and output the row and column values.

In the `main` function, we call `createGrid` to create the grid and store its head node in the `head` variable. Then we call `displayGrid` to output the row and column values of each node in the grid.
