Answer:

\(X_t=2.17391304*10^{-4}\)

\(X_r=2.89855072*10^{-4}\)

\(e_t=0.0026\)

\(e_r=0.0035\)

Explanation:

From the question we are told that:

Dimension \(12*12\)

Thickness \(l_t=5mm=5*10^-3\)

Normal tensile force on top side \(F_t= 15kN\)

Normal tensile force on right side  \(F_r= 20kN\)

Elastic modulus, \(E=115Gpap=>115*10^9\)

Generally the equation for Normal Strain X is mathematically given by

 \(X=\frac{Force}{Area*E}\)

Therefore

For Top

 \(X_t=\frac{Force_t}{Area*E}\)

Where

 \(Area=L*B*T\)

 \(Area=12*10^{-2}*5*10^{-3}\)

 \(Area=6*10^{-4}\)  

 \(X_t=\frac{15*10^3}{6*10^{-4}*115*10^9}\)

 \(X_t=2.17391304*10^{-4}\)

For Right side\(X_r=\frac{Force_r}{Area*E}\)

Where

Area=L*B*T

 \(Area=12*10^{-2}*5*10^{-3}\)

 \(Area=6*10^{-4}\)  

 \(X_r=2.89855072*10^{-4}\)

 \(X_r=2.89855072*10^{-4}\)

Generally the equation for elongation is mathematically given by

 \(e=strain *12\)

For top

 \(e_t=2.17391304*10^{-4}*12\)

 \(e_t=0.0026\)

For Right

 \(e_r=2.89855072*10^{-4} *12\)

 \(e_r=0.0035\)

To determine the various parameters for the amplitude modulation (AM) system, let's analyze the given information step by step:

(a) Frequency of Sidebands:

The frequency of the sidebands in an AM signal can be calculated using the formula:

f_sideband = f_carrier ± f_modulation

In this case, the carrier frequency is 105 Hz and the modulation frequency is 1000 Hz. So the frequency of the sidebands will be:

f_sideband = 105 ± 1000

Therefore, the two sidebands will have frequencies of 1105 Hz and 905 Hz.

(b) Bandwidth (BW):

The bandwidth of an AM signal can be calculated using the formula:

BW = 2 × f_modulation

In this case, the modulation frequency is 1000 Hz. So the bandwidth will be:

BW = 2 × 1000 = 2000 Hz

(c) Modulation Index (m):

The modulation index (m) can be calculated using the formula:

m = (A_modulation) / (A_carrier)

In this case, the amplitude of the modulation signal is 10 and the amplitude of the carrier signal is 50. So the modulation index will be:

m = 10 / 50 = 0.2

(d) Amplitude of Each Sideband (Em):

The amplitude of each sideband can be calculated using the formula:

Em = (m × A_carrier) / 2

In this case, the modulation index (m) is 0.2 and the amplitude of the carrier signal is 50. So the amplitude of each sideband will be:

Em = (0.2 × 50) / 2 = 5

(e) Transmission Efficiency:

The transmission efficiency of an AM system can be calculated using the formula:

Transmission Efficiency = (Power of Sidebands) / (Total Power)

In this case, since the carrier and one sideband are present, the total power can be calculated as the sum of the powers of the carrier and one sideband.

The power of the carrier can be calculated using the formula: P_carrier = (A_carrier)^2 / (2 × R), where R is the load resistance.

The power of one sideband can be calculated using the formula: P_sideband = (Em)^2 / (2 × R)

In this case, the load resistance is given as 300Ω. So the total power can be calculated as:

Total Power = P_carrier + P_sideband

(f) Total Power Delivered to a Load of 300Ω:

To calculate the total power delivered to the load, we need to substitute the values of A_carrier, Em, and R into the formulas for P_carrier and P_sideband, and then calculate the sum.

(g) Output Frequency Spectrum:

To draw the output frequency spectrum, we need to plot the amplitude versus frequency graph. In this case, we will have a carrier frequency of 105 Hz and two sideband frequencies at 1105 Hz and 905 Hz. The amplitudes of the carrier and sidebands can be calculated using the modulation index and amplitude values.

(h) Percentage Power Saving:

To calculate the percentage power saving when one sideband and carrier are suppressed, we need to calculate the power of the suppressed components and compare it to the total power without suppression.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.

Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.

The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

The placement of a marker point largely depends on the purpose of the marker. If you're marking a location on a map, for instance, the marker should be placed at the precise location you wish to identify.

This could be the address of a business, the location of a landmark, or a specific point of interest. If the marker is being used to identify a point on a physical object, such as a tool or machine, it should be placed at the exact point being referenced.

In general, it's important to be as precise as possible when placing a marker point, as even slight deviations can lead to confusion or errors.

Answer:

Mach number = 0.68168

The flow should be treated as compressible.

Explanation:

Given that:

The altitude of a commercial jet = 35000

The properties of air at that given altitude are as follows:

Pressure = 24.577 kPa

Temperature T = 50.78176° C

Temperature T = ( 50.78176 + 273 )K = 328.78176 K

\(\varphi = 0.38428 \ kg/m^3\)

The velocity is also given as: 550 mph = 245.872 m/s

Therefore, the sonic velocity is firstly determined by using the formula:

\(a = \sqrt{ \vartheta \times R \times T\\)

\(a = \sqrt{1.4 \times 287 \times 323.78176\)

\(a = \sqrt{130095.5112\)

a = 360.68755 m/s

Then, we can calculate the Mach number by using the expression:

\({Mach \ number = \dfrac{V}{a}}\)

\(Mach \ number = \dfrac{245.872}{360.68755}\)

Mach number = 0.68168

b) Ideally, all flows are compressible because the Mach number is greater than 0.3, suppose the Mach number is lesser than 0.3, then it is incompressible.
