The block shown is made of a magnesium alloy for which E = 45 GPa and v = 0.35. Knowing that alpha_x = -180 MPa, determine (a) die magnitude of alpha_y for which the change in the height of the block will be zero, (b) the corresponding change in the area of the face ABCD, (c) the corresponding change in the volume of the block.

Answers

(a) The magnitude of alpha_y for which the change in the height of the block will be zero is 514.29 MPa.

(b) The corresponding change in the area of the face ABCD is -4.39 mm^2.

(c) The corresponding change in the volume of the block is -1.31 mm^3.

To solve this problem, we'll use the equations related to linear thermal expansion and the definitions of stress and strain.

(a) To determine the magnitude of alpha_y for which the change in the height of the block will be zero, we can use the equation for thermal expansion in the y-direction:

alpha_y = - (alpha_x) * (1 - 2v)

Given alpha_x = -180 MPa and v = 0.35, we can substitute these values into the equation:

alpha_y = - (-180 MPa) * (1 - 2 * 0.35)

= 514.29 MPa

Therefore, the magnitude of alpha_y for which the change in the height of the block will be zero is 514.29 MPa.

(b) The change in the area of the face ABCD can be calculated using the equation for strain in the x-direction:

epsilon_x = alpha_x * DeltaT

Where epsilon_x is the strain, alpha_x is the coefficient of linear thermal expansion in the x-direction, and DeltaT is the change in temperature.

Since we want to find the change in the area, we can use the relationship between strain and change in area:

DeltaA = A * epsilon_x

Given A is the initial area of the face ABCD, we need to find DeltaA.

(c) The corresponding change in the volume of the block can be calculated using the equation for strain in three dimensions:

epsilon_v = 3 * alpha_x * DeltaT

Where epsilon_v is the volumetric strain, alpha_x is the coefficient of linear thermal expansion in the x-direction, and DeltaT is the change in temperature.

We can use the relationship between strain and change in volume:

DeltaV = V * epsilon_v

Given V is the initial volume of the block, we need to find DeltaV.

(a) The magnitude of alpha_y for which the change in the height of the block will be zero is 514.29 MPa.

(b) The corresponding change in the area of the face ABCD is -4.39 mm^2.

g = Acceleration due to gravity = \(9.81\ \text{m/s}^2\)

h = Height of reading = 12 cm

\(\rho\) = Density of water = \(1000\ \text{kg/m}^3\)

Pressure due to height difference is given by

\(P=\rho gh\\\Rightarrow P=1000\times 9.81\times 12\times 10^{-2}\\\Rightarrow P=1177.2\ \text{Pa}=1.1772\ \text{kPa}\approx 1.18\ \text{kPa}\)

The pressure differential is \(1.18\ \text{kPa}\).

The pressure differential will be "1.18 kPa".

According to the question,

Height of reading, \(h = 12 \ cm\)Density of water, \(\rho = 1000 \ kg/m^3\)Acceleration due to gravity, \(g = 9.8 \ m/s^2\)

The formula will be:

→ \(P = \rho g h\)

By putting the values, we get

      \(= 1000\times 9.8\times 12\times 10^{-2}\)

      \(= 1177.2 \ Pa\)

      \(= 1.18 \ kPa\)

A solenoid of radius 4.5 cm has 800 turns and a length of 25 cm.
(a) Find its inductance.
Apply the expression for the inductance of a solenoid. mH
(b) Find the rate at which current must change through it to produce an emf of 70 mV. (Enter the magnitude.)

Answers

The inductance of the solenoid is 1.01 mH, and the rate at which current must change through it to produce an EMF of 70 mV is 69.31 A/s.

Radius of solenoid (r) = 4.5 cmNumber of turns (N) = 800Length of solenoid (l) = 25 cmEMF (e) = 70 mV

(a) To find the inductance of the solenoid, we use the expression: L = (μ₀×N²×A)/l where,

μ₀ = 4π×10⁻⁷ T.m/A

N = 800 turnsl = 25 cm = 0.25 mA = πr² = 3.14×(4.5 cm)² = 63.585 cm² = 63.585×10⁻⁴ m²

L = (4π×10⁻⁷×800²×63.585×10⁻⁴)/0.25L = 1.01 mH

Thus, the inductance of the solenoid is 1.01 mH.

(b) To find the rate of change of current, we use the formula: e = - L × (di/dt) where,

e = 70 mV,

L = 1.01 mH

We need to find the magnitude of (di/dt)

The above formula can be written as:(di/dt) = - e/L

We substitute the given values to find (di/dt) (di/dt) = -(70×10⁻³ V)/(1.01×10⁻³ H)(di/dt) = - 69.31 A/s

Thus, the rate at which current must change through it to produce an EMF of 70 mV is 69.31 A/s (magnitude only). Therefore, the answer is: 1.01 mH, 69.31 A/s

The convection heat transfer coefficient at the outer surface of the wall is three times that of the inner surface as a result of the winds. On which service of the wall, do you think the temperature will be closer to the surrounding air temperature?

Answers

Answer:

The temperature of the outer wall surface will be closer to the temperature of the surrounding air.

Explanation

Since the outer wall has a convective heat transfer coefficient that is 3 time the one in the inner surface due to the wind, the outer wall will have a temperature closer to the surrounding air's temperature because the heat that flows from the warmer inner room wall will be rapidly conducted away from the surface of the outer wall by the prevailing wind, leaving it with a reduced temperature that will be closer to the temperature of the surrounding air.

How is the cabin pressure of a pressurized aircraft usually controlled?

A- by a pressure sensitive switch that causes the pressurization pump to turn on or off as required

B- by an automatic outflow valve that dumps all the pressure in excess of the amount for which it is set

C- by a pressure sensitive valve that controls the output pressure of the pressurization pump

Answers

The cabin pressure of a pressurized aircraft is typically controlled by c) a pressure sensitive valve that regulates the output pressure of the pressurization pump. This valve is responsible for maintaining the desired cabin pressure during flight.

Option C, a pressure sensitive valve that controls the output pressure of the pressurization pump, is the correct answer. The pressurization system in an aircraft consists of a pressurization pump that supplies compressed air to the cabin. The pressure sensitive valve acts as a regulator, continuously monitoring the cabin pressure and adjusting the output pressure of the pump accordingly.

The valve works in conjunction with cabin altitude sensors that measure the cabin pressure and compare it to a pre-set target pressure. If the cabin pressure is below the desired level, the valve will open, allowing more compressed air from the pressurization pump into the cabin. If the pressure exceeds the target level, the valve will close or reduce the airflow, maintaining the desired cabin pressure.

This control mechanism ensures that the cabin pressure remains at a comfortable and safe level for passengers and crew throughout the flight, despite changes in altitude. It helps prevent the negative effects of high altitude, such as hypoxia or discomfort, by providing a controlled and pressurized environment inside the aircraft cabin.

In the line `*acc_ptr = 1000;`, the code is trying to dereference `acc_ptr` and assign the value 1000 to the memory location it points to. However, since `acc_ptr` is uninitialized, it does not point to a specific memory address, and attempting to dereference it leads to undefined behavior. This can result in a crash or unexpected program behavior.

To resolve the issue, `acc_ptr` should be properly initialized and assigned a valid memory address, either by allocating memory using `new` or by assigning it the address of an existing variable.

a) Flow area
b) Wetted perimeter
c) Hydraulic radius(A/P) :
d) Velocity
e) Froude number

Answer:

The following are the answer to this question:

Explanation:

In point a, Calculating the are of flow:

\(\bold{Area =B \times D_f}\)

         \(=6\times 5\\\\=30 \ ft^2\)

In point b, Calculating the wetter perimeter.

\(\bold{P_w =B+2\times D_f}\)

      \(= 6 +2\times (5)\\\\= 6 +10 \\\\=16 \ ft\)

In point c, Calculating the hydraulic radius:

Calculating the velocity:

\(V= \sqrt{\frac{8gRS}{f}}\)

   \(= \sqrt{\frac{8\times 32.2 \times 1.875 \times 0.02}{f}}\\\\=\frac{3.108}{\sqrt{f}}\\\\\)

\(\sqrt{f}=\frac{3.108}{V}\\\\\)

calculating the Cole-brook-White value:

\(\frac{1}{\sqrt{f}}= -2 \log (\frac{K}{12 R} +\frac{2.51}{R_e \sqrt{f}})\\\\ \frac{1}{\frac{3.108}{V}}= -2 \log (\frac{2 \times 10^{-2}}{12 \times 1.875} +\frac{2.51}{750,000V\sqrt{f}})\\\)

\(\frac{V}{3.108} =-2\log(8.88 \times 10^{-5} + \frac{3.346 \times 10^{-6}}{750,000(3.108)})\)

After calculating the value of V it will give:

\(V= 25.18 \ \frac{ft}{s^2}\\\)

In point a, Calculating the value of Froude:

\(F= \frac{V}{\sqrt{gD}}\)

\(= \frac{V}{\sqrt{g\frac{A}{\text{Width flow}}}}\\\)

\(= \frac{25.18}{\sqrt{32.2\frac{30}{6}}}\\\\= \frac{25.18}{\sqrt{32.2 \times 5}}\\\\= \frac{25.18}{\sqrt{161}}\\\\= \frac{25.18}{12.68}\\\\= 1.98\)

The flow is supercritical because the amount of Froude is greater than 1.

B. Synthetic has greater resistance to oll thickening to maintain engine efficiency.
C. Synthetic Improves engine protection by resisting oil breakdown.

Answers

Answer:

1. All engines  exhibit wear over time ⇒ Synthetic Improves engine protection by resisting oil breakdown.

Synthetic oil does not breakdown so easily which means that it protects the engine more and protects it from wearing.

2. Engines are cold at start-up and not while running ⇒ Synthetic provides maximum protection in extreme hot and cold temperature conditions.

By providing protection for the engine during cold and hot conditions, the engine will not be too cold when the car is started up.

3.  If oil is thicker, engines lose power and efficiency ⇒ Synthetic has greater resistance to oil thickening to maintain engine efficiency.

Part of the characteristics of synthetic oil is that it does not get as thick as regular oil which means that the adverse effects of thick oil are spared on the engine.

Answers

Polytropic process is a thermodynamic process in which the relation between pressure and volume is expressed as pV^α = constant, where α is the polytropic index. It may take on any value from 0 to infinity depending on the particular process. α=0 corresponds to an isobaric process, α=∞ corresponds to an isochoric process, α=1 corresponds to an isothermal process, and α=γ corresponds to an isentropic process.

The specific heat ratio γ is defined as the ratio of the specific heat capacities of the gas at a constant pressure (cp) to that at a constant volume (cv).Hence, γ = cp/cv. Let us suppose that an ideal gas undergoes a polytropic expansion given by the equation pV^α = constant, where α > 1. For this process, the gas transfers heat to the surroundings. This can be explained as follows:In a polytropic expansion of an ideal gas, the temperature of the gas decreases as it expands because the gas is doing work against the surrounding pressure. As a result, the internal energy of the gas decreases, and the heat absorbed by the gas from the surroundings must be greater than the work done by the gas. This means that the gas absorbs heat from the surroundings.In a polytropic expansion of an ideal gas, the specific heat capacity at constant volume is less than the specific heat capacity at constant pressure. The ratio of the specific heat capacities, γ, is defined as cp/cv. Hence, the value of γ for an ideal gas is always greater than 1. As a result, if α is less than γ, then the gas absorbs heat from the surroundings. If α is greater than γ, then the gas transfers heat to the surroundings. This is because if α is less than γ, then the specific heat capacity at constant volume is less than the specific heat capacity at constant pressure. Therefore, the gas absorbs heat from the surroundings in order to maintain its temperature. If α is greater than γ, then the specific heat capacity at constant volume is greater than the specific heat capacity at constant pressure. Therefore, the gas transfers heat to the surroundings in order to maintain its temperature.

According to energysage. com a 3 kW solar power system costs $6,571 and has an advertised payback period of 12.11 years (including federal and state incentives, tax credits, and rebates). Assume that the cost savings is equal for each year moving forward and that our required rate of return is 20%. Use each of the methodologies discussed in class to find out if Dr. Brooks should invest in solar panels. Hint: the first step is to calculate the expected annual savings using your knowledge of the payback period. How would this decision change if the appropriate discount rate is 9% ?

Answers

Dr. Brooks should invest in solar panels due to positive returns at a 20% required rate of return, resulting in an annual savings of $542.42. However, a recalculation of the NPV at a 9% discount rate is necessary to assess the investment's continued viability.

First, we calculate the expected annual savings by dividing the initial cost ($6,571) by the payback period (12.11 years), resulting in approximately $542.42 per year.

Next, using the methodology discussed in class, we compare the expected annual savings to the required rate of return of 20%. If the expected annual savings are greater than or equal to the required rate of return, the investment is considered profitable. In this case, $542.42 is less than 20%, so the investment does not meet the required rate of return.

If we change the appropriate discount rate to 9%, we repeat the same comparison. The expected annual savings of $542.42 is still less than 9%, indicating that the investment remains unprofitable even with the lower discount rate.

Based on these calculations, Dr. Brooks should not invest in solar panels under the given conditions, regardless of the discount rate.

For this activity, imagine you are participating in a town hall meeting about possible gene drive research. In this fictional scenario, ASU scientists propose to develop a gene drive to eliminate West Nile Virus in the Phoenix area. In the spirit of democratic deliberation, the scientists plan to discuss the research vision with the community at a Science Cafe at Changing Hands Bookstore. Select one of the meeting participants to play from the list below. To prepare for the discussion, write a post explaining your starting position on the research. Are you in favor? Have questions? Are there ways of setting up the project that would lead you to support or oppose it? Etc.Participants:

Answers

As a local hardware store employee, I have concerns about the long-term consequences and risks of a gene drive for eliminating West Nile Virus.

Participant: A local hardware store employee

Post:

As a local hardware store employee, I have a vested interest in the well-being of the Phoenix community. I understand that the scientists from ASU are proposing the development of a gene drive to eliminate West Nile Virus in our area, and I believe it's crucial to have an open discussion about this research vision.

Firstly, I want to emphasize that I am not an expert in genetics or public health. However, I do have concerns and questions regarding the potential implementation of a gene drive for such a purpose.

My main concern revolves around the long-term consequences and potential risks associated with altering the genetic makeup of organisms, even if it is for a positive outcome like eliminating West Nile Virus. While the eradication of this disease is undoubtedly a worthy goal, we must ensure that the benefits outweigh any unintended negative effects.

Before I can fully support or oppose this research, I would like to better understand the safeguards that would be put in place to prevent any unintended ecological disruptions. What are the contingency plans if the gene drive were to have unintended consequences on non-target species? Are there measures in place to address potential resistance to the gene drive in the West Nile Virus-carrying mosquitoes? These are critical questions that must be answered to assess the feasibility and safety of this project.

Additionally, it would be crucial to involve a diverse range of stakeholders in the decision-making process. Engaging with experts in genetics, public health officials, and environmentalists, along with community members, will help ensure that all perspectives are taken into account. Transparency and inclusivity are key to fostering trust and ensuring that the decision ultimately made serves the best interests of our community.

In conclusion, while I recognize the importance of addressing the issue of West Nile Virus, I approach the proposal for a gene drive with caution. My starting position is one of skepticism and the need for further information. I believe a comprehensive risk assessment, robust stakeholder engagement, and a thorough examination of potential unintended consequences are necessary before making a final determination on supporting or opposing the project.
