The three failure theories which are generally used to calculate stresses are- Maximum principal stress theory Maximum principal strain theory Maximum shear stress theory Out of the three failure theories, Maximum principal stress theory is appropriate because we have been given the values of the stresses directly.

Given stress states are:

σx = 10,

σy = 5,

τxy = 4.5,

sut = 20,

suc = 80,

sy = 18

The stress values and failure stresses can be used to calculate the factor of safety and effective stress.The effective stress is calculated by the following formula:σ1 and σ2 are the principal stresses. As we do not have these values, we have to use the following formulas to find out these principal stresses using the given stress values.

Max. principal stress=σ1

= (σx + σy)/2 + √((σx - σy) /2)² + τ²xy/2

= 7.5 + √((10-5)/2)² + 4.5²/2

= 7.5 + 4.301 = 11.8 kpsi

Min. principal stress=σ2

= (σx + σy)/2 - √((σx - σy) /2)² + τ²xy/2

= 7.5 - √((10-5)/2)² + 4.5²/2

= 7.5 - 2.301

= 5.2 kpsi

Now we can calculate the effective stress = (σ1 - σ2)/2

= (11.8-5.2)/2

= 3.3 kpsi

Factor of Safety can be calculated as:

Factor of safety (FoS) = failure stress/ Effective stress

We have three different failure stresses

-Syt = 18 kpsi - tensile yield stressSuc = 80 kpsi - Unconfined Compressive strengthSut = 20 kpsi - Ultimate tensile strength

The minimum value of the Factor of Safety (FoS) out of the three is taken because the structure should fail first under the most unfavorable condition (i.e. minimum FoS).

The values of FoS for all three failure theories are calculated and the minimum value is taken.Max principal stress theory:

FoS = minimum failure stress/ Effective stress

Minimum FoS = min (18/3.3, 80/3.3, 20/3.3)

Minimum FoS = 5.45 (Approx)

Hence the factor of safety against static failure is 5.45.

Answer:

Option B: False

Explanation:

A heat engine is a device which operates in a manner that heat is converted into mechanical work.

A simple example of a heat engine is a drinking bird. The oscillatory motion of the drinking bird is as a result of the thermal expansion and contraction of a chemical compound in its beak, which creates an imbalance in its position of equilibrium. This causes it to oscillate.

Heat engines usually work by extracting heat once there is a temperature gradient available in the system and using it to perform work. Another good example is the internal combustion engine. It extracts heat from the explosion of the burning fuels and uses it to power the car.

I'm sorry, but I am unable to generate visual content or sketches as a text-based AI model. However, I can describe the schematic of a MOSFET-based single quadrant amplifier for a DC motor.

A MOSFET-based single quadrant amplifier for a DC motor typically consists of a power MOSFET, a gate driver circuit, and the DC motor itself.

The power MOSFET acts as the main amplifier component for controlling the motor's speed and direction. The gate driver circuit is responsible for providing the necessary voltage and current to drive the MOSFET.

In the schematic, the MOSFET is connected in a common source configuration, with the source terminal connected to the ground and the drain terminal connected to one terminal of the DC motor. The other terminal of the DC motor is connected to a DC power supply. The gate terminal of the MOSFET is connected to the output of the gate driver circuit.

The calculated thrust that we are required to find in this question are solved as:

Rate = excess power / weight

= dn / dt

= V∞sin θ

V∞sin θ = Tn - Tr / w * V∞

sin θ  = Tn - D / w

Tr = D

sin θ = T / w - D / w

T / w = sin θ + D / w

We would have the formula here as

ma x √vRTw

= 0.85 x √1.4 x 287 x 226.73

= 256.5 m/s

Next we have to solve for the angle of climb

∅ = sin⁻¹ (1.524 / 256.5)

= 5.94 x 10⁻³

T = w (θ + 1/10)

= 2446521.9 * 5.94 x 10⁻³ * 1/18

= 150.45

The static thrust at the sea level = 2446521.9 / 18

= 135.917 N

Therefore the required thrust at the cruising altitude is equal to  150.45

Answer: 75,000 Hz

Explanation:

To calculate the frequency of the supply voltage, we need to use the formula:

frequency = 1 / time period

where the time period is the time it takes for one complete cycle of the waveform. For a sine wave, the time period is given by:

time period = 2π / angular frequency

where the angular frequency is the rate of change of the angle with respect to time and is given by:

angular frequency = 2π × frequency

Comparing the given voltage expression v = 240 sin (471,239t) V to the general form of a sine wave:

v = Vm sin(ωt + θ)

where Vm is the amplitude, ω is the angular frequency, t is time, and θ is the phase angle, we can see that the amplitude is 240 V, the angular frequency is 471,239 rad/s, and there is no phase angle (θ = 0).

Using the formula for angular frequency, we can find the frequency:

angular frequency = 2π × frequency

471,239 = 2π × frequency

frequency = 471,239 / (2π) ≈ 75,000 Hz

Therefore, the frequency of the supply voltage is approximately 75,000 Hz.

Hope this helps, :^)

Among the given circuit elements, the 1000-ohm resistor would draw the largest rms current when a 1000 Hz sinusoidal voltage is connected across it. This is because resistors follow Ohm's Law (V=IR), where the current (I) is directly proportional to the voltage (V) and inversely proportional to the resistance (R).

Unlike inductive or capacitive elements, resistors don't have reactance that changes with frequency.In contrast, the current drawn by inductive and capacitive elements depends on their reactance, which varies with frequency. The inductive reactance (XL) is given by XL = 2πfL, and the capacitive reactance (XC) is given by XC = 1/(2πfC). At 1000 Hz, the 50 mH inductor has an inductive reactance of 314 ohms, and the 500 nF capacitor has a capacitive reactance of approximately 318 ohms.For the series combination of the 50 mH inductor and 500 nF capacitor, the net reactance is given by the difference between the inductive and capacitive reactances (XL - XC). In this case, the net reactance is close to 0, as the inductive and capacitive reactances nearly cancel each other out. This results in a very low current draw for the series combination.Therefore, among the given circuit elements, the 1000-ohm resistor will draw the largest rms current when a 1000 Hz sinusoidal voltage is connected across it.

The temperature range for cement clinker formation typically falls between 1,450°C (2,642°F) and 1,550°C (2,822°F).

What is temperature?
Temperature is a measure of the average kinetic energy of the particles in a substance or system. In other words, it is a measure of how hot or cold a substance or system is relative to a reference point.

Cement clinker is a dark grey nodular material that is produced by heating a mixture of limestone, clay, and other minerals in a kiln to very high temperatures. The high temperatures cause a series of chemical reactions to take place, which results in the formation of new compounds and the breakdown of others. This process, known as clinkerization, produces cement clinker as the final product.

The exact temperature range for clinker formation can vary depending on several factors, such as the chemical composition of the raw materials, the type of kiln used, and the rate of heating. However, the temperature range mentioned above is considered to be the standard range for most cement manufacturing processes.
