Answer:

the output of the IF amplifier consist of 675 kHz

Explanation:

Given the data in the question;

AM signal carrier frequency \(_{RF\)  = 460 kHz

Local oscillator frequency\(_{lo\) = 1135 kHz

Now, The output of the IF amplifier consists of difference of local oscillator frequency & AM carrier signal frequency;

FREQUECY\(_{IF\) = FREQUECY\(_{lo\) - FREQUECY\(_{RF\)

so we substitute in our given values

FREQUECY\(_{IF\) = 1135 kHz - 460 kHz

FREQUECY\(_{IF\) = 675 kHz

Therefore, the output of the IF amplifier consist of 675 kHz

a) The expected queue length is 2.63 vehicles.

b) The probability of having 4 or fewer cars at the gate is 0.822.

c) The average waiting time of a vehicle is 0.8 minutes.

(a) The expected length of queue at the ticket gate is given by λw, where λ is the arrival rate and w is the expected waiting time in the queue. The arrival rate is 29 veh/h and the expected waiting time is 1.6/60 h/min = 0.027 h. Therefore, the expected length of queue is 29 x 0.027 = 0.783 vehicles, which is approximately 0.79 vehicles.

(b) The probability of no more than 4 cars at the gate, including the vehicle being served, can be calculated using the Poisson distribution. The parameter λ is still 29 veh/h. The probability of no more than 4 cars is given by P(0) + P(1) + P(2) + P(3) + P(4), where P(k) is the Poisson probability mass function with parameter λ and k is the number of cars. Using a calculator, we get P(0) + P(1) + P(2) + P(3) + P(4) = 0.8216, which is approximately 0.822.

(c) The average waiting time of a vehicle can be calculated by dividing the expected length of queue by the arrival rate, and adding the expected service time of 1.6 minutes. Therefore, the average waiting time of a vehicle is (0.783/29) + 1.6 = 0.8 minutes.

In the circuits of figure P2. 18, the directions of current and polarities of voltage have already been defined. To find the actual values of the indicated currents and voltages, we need to use the Ohm's Law and Kirchhoff's Laws.Using Kirchhoff's Voltage Law, we can write,

V1 - I1R1 - V2 = 0 ...(1)

V3 - I2R2 - V2 = 0 ...(2)

From equation (1), we get

I1 = (V1 - V2)/R1 ...(3)

From equation (2), we get

I2 = (V3 - V2)/R2 ...(4)

Using Kirchhoff's Current Law, we can write,

I1 + I3 - I2 = 0 ...(5)

Substituting the values of I1 and I2 from equations (3) and (4) into equation (5), we get

(V1 - V2)/R1 + I3 - (V3 - V2)/R2 = 0 ...(6)

Simplifying equation (6), we get

I3 = [(V3 - V2)/R2 - (V1 - V2)/R1] ...(7)

Now, using Ohm's Law, we can write,

V2 = I1R1 ...(8)V3 = I2R2 ...(9)

Substituting the values of I1 and V2 from equations (3) and (8) into equation (1), we get

V1 - [(V1 - V2)/R1]R1 - I1R1 = 0

Simplifying the above equation, we get

V1 - V1 + V2 - I1R1 = 0V2 = I1R1

From equation (3), we have

I1 = (V1 - V2)/R1 = (10 - 3)/10 = 0.7 A

From equation (4), we have

I2 = (V3 - V2)/R2 = (5 - 3)/5 = 0.4 A

From equation (7), we haveI

3 = [(V3 - V2)/R2 - (V1 - V2)/R1] = [(5 - 3)/5 - (10 - 3)/10] = 0.16 A

From equation (8), we have

V2 = I1R1 = 0.7 × 10 = 7 V

Control chart diagramming tool can be used to determine the work process's accuracy.

The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.

Control charts show if a process is in control or out of control. They show the variance (or variation) of process output over time. Control charts compare this variance against upper and lower limits to see if it fits within the expected, specific, predictable and normal variation levels.

The resistance for a perfect circuit will be calculated as R= I/V = 6/2 = 2. A variable power supply is one that has several controls that allow the user to quickly change the output voltage and, occasionally, current.

The most common tool for adjustment is a potentiometer, although other tools include analog control voltage, digital input, autotransformer, etc. The measured voltage is the total of the voltages across the ammeter and the resistance, albeit, with a non-ideal ammeter, the ammeter's resistance is not zero. Otherwise known as V>V R, measured voltage (V) is greater than the voltage across the resistor (V R).

As a result, the measured resistance (2) is higher than the real resistance.

Answer:

torque to raise the load = 16.411 Nm

torque to lower the load = 8.40 Nm

overall efficiency = 0.24

Explanation:

Given:

max load on vertical direction of the screw = Force = F = 5kN

frictional  diameter of the collar = 45 mm

Diameter = 25 mm

length of pitch = 5 mm

coefficient of friction for thread µ  = 0.09

coefficient of friction for collar µ\(_{c}\) = 0.06

To find:

torque to "raise" the load

torque to and "lower"

overall efficiency

Solution:

Compute torque to raise the load:

\(T_{R} = \frac{ Fd_{m}}{2} (\frac{L+(\pi ud_{m}) }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)

where

\(T_{R}\) is the torque

F is the load

\(d_{m}\) is diameter of thread

\(d_{c}\) is diameter of collar

L is the thread pitch distance

µ is coefficient of friction for thread

µ\(_{c}\)  is coefficient of friction for collar

Putting the values in above formula:

\(T_{R}\) = 5(25) / 2 [5+ (π(0.09)(25) / π(25)-0.09(5)] + 5(0.06)(45) / 2

    = 125/2 [5 + (3.14)(0.09)(25)/ 3.14(25)-0.45] + 13.5/2

    = 62.5 [(5 + 7.065) / 78.5 - 0.45] + 6.75

    = 62.5 [12.065 / 78.05 ] + 6.75

    = 62.5 (0.15458) + 6.75

    = 9.66125 + 6.75

    = 16.41125

\(T_{R}\) = 16.411 Nm

Compute torque to lower the load:

\(T_{L} = \frac{ Fd_{m}}{2} (\frac{(\pi ud_{m}) - L }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)

     = 5(25) / 2 [ (π(0.09)(25) - L / π(25)-0.09(5) ] + 5(0.06)(45) / 2

     = 125/2 [ ((3.14)(0.09)(25) - 5) / 3.14(25)-0.45 ] + 13.5/2

     = 62.5 [ (7.065 - 5) / 78.5 - 0.45 ] + 6.75

    = 62.5 [ 2.065 / 78.05 ] + 6.75

     = 62.5 (0.026457) + 6.75

     = 1.6535625 + 6.75

     = 8.40 Nm

Since the torque required to lower the the load is positive indicating that an effort is applied to lower the load, Hence the thread is self locking.

Compute overall efficiency:

overall efficiency = F(L) / 2π \(T_{R}\)

                             = 5(5) / 2(3.14)( 16.411)

                             = 25/ 103.06108

overall efficiency = 0.24

Answer:

\( T_A_C = 6.296 kN \)

\( R = 10.06 kN \)

Explanation:

Given:

\( T_A_B = 8.7 kN\)

Required:

Find the tension TAC and magnitude R of this downward force.

First calculate \( \alpha, \beta, \gamma \)

\( \alpha = tan^-^1 =\frac{40}{50} = 38. 36 \)

\( \beta = tan^-^1 =\frac{50}{30} = 59.04 \)

\( \gamma = 180 - 38.36 - 59.04 = 82.6 \)

To Find tension in AC and magnitude R, use sine rule.

\( \frac{sin a}{T_A_C} = \frac{sin b}{T_A_B} = \frac{sin c}{R} \)

Substitute values:

\(\frac{sin 38.36}{T_A_C} = \frac{sin 59.04}{8.7} = \frac{82.6}{R}\)

Solve for T_A_C:

\( T_A_C = 8.7 * \frac{sin 38.36}{sin 59.04} = \)

\( T_A_C = 8.7 * 0.724 = 6.296 kN \)

Solve for R.

\( R = 8.7 * \frac{sin 82.6}{sin 59.04} = \)

\( R = 8.7 * 1.156 \)

R = 10.06 kN

Tension AC = 6.296kN

Magnitude,R = 10.06 kN

It is important to note that these tolerances are established by the Federal Aviation Administration (FAA) and must be met in order for the VOR system to be considered operational and reliable. Any discrepancies or deviations from these tolerances should be addressed and corrected before the aircraft is flown.

When checking both VOR receivers by use of the VOT (VOR Operational Test), the acceptable tolerances are as follows:
1. Course deviation indicator (CDI) centering - The CDI should be centered within plus or minus 4 degrees of the 0-degree position.
2. Course indication - The course indication should be accurate to within plus or minus 6 degrees of the VOR radial selected.
3. Reverse sensing - When flying outbound from the VOR station, the CDI should show full scale deflection in the direction opposite to the selected course. When flying inbound, the CDI should show normal deflection toward the selected course.
4. Signal strength - The signal strength should be sufficient to provide a useable and reliable signal at all times during the flight.
