The maximum stresses of the section near the fixed end are Bending stress, -10.16 ksi and Shear stress, 1.89 ksi.

To determine the maximum stresses at a section near the fixed end of the beam, calculate the bending stress and the shear stress.

First, let's find the reactions at the fixed end of the beam. Since the beam is completely fixed, the reactions will be equal and opposite to the applied force, which means:

Rx = -Fx = -400 lb

Ry = -Fy = 300 lb

Rz = -Fz = 1200 lb

Next, calculate the bending moment caused by the applied force. Since the force passes through the centroid of the beam, we can assume that the moment arm is equal to half the depth of the beam, which is 4.055 inches. Therefore, the bending moment at the section near the fixed end is:

M = Fz × 4.055 in = -4875 lb·in

Using the moment of inertia about the x-axis (centroidal-longitudinal axis), calculate the bending stress:

σx = M × (H/2) / Ix = -10.16 ksi

Next, calculate the shear stress using the shear force caused by the applied force. Since there is no other load on the beam, the shear force at the section near the fixed end is equal to the reaction force in the y-direction, which is 300 lb. Using the area of the web, calculate the shear stress:

τ = V × (W × t) / (2 × Iy) = 1.89 ksi

where V is the shear force, W is the width of the web, t is the thickness of the web, and Iy is the moment of inertia about the y-axis (centroidal-vertical axis). Note that we assume the shear stress distribution is uniform across the thickness of the web.

Therefore, the maximum stresses at the section near the fixed end of the beam are:

Bending stress: σx = -10.16 ksi

Shear stress: τ = 1.89 ksi

The bending stress is compressive and larger in magnitude than the yield stress of the material, which means the beam will fail due to bending. The shear stress is relatively small and does not contribute significantly to the failure of the beam.

Answer:

Simple math. One microsecond is one 1 millionth of a second and in your example you have 5 microseconds so you will need to divide 1 million by 5 to arrive at the answer. In this case that means that there will be 200,000 of these 5 mico second cycles per second.

The period is the time taken to complete one oscillation. Hence, the period is 2 μs

Recall :

1 μs = \( 1 \times 10^{-6} s \)

10 μs = \( 1 \times 10^{-5} s \)

Hence, Frequency, is the number of cycles per second ;

5 cycles = \( 1 \times 10^{-5} s \)

x = 1 second

Cross multiply :

0.00001x = 5

x = 500,000 Hz

Hence, Frequency, F = 500000 Hz

Period = 1 / Frequency

Period = 1/500000

Period = 0.000002 seconds

Answer:

The right solution is "2625 kN".

Explanation:

According to the question,

The average pressure will be:

= \(density\times g\times \frac{h}{2}\)

By putting values, we get

= \(1000\times 9.8\times \frac{12.2}{2}\)

= \(1000\times 9.8\times 6.1\)

= \(59780\)

hence,

The average force will be:

= \(Pressure\times Area\)

= \(59780\times 3.6\times 12.2\)

= \(2625537 \ N\)

Or,

= \(2625 \ kN\)

Answer:

The volume percent of graphite is 91.906 per cent.

Explanation:

The volume percent of graphite (\(\% V_{Gr}\)) is determined by the following expression:

\(\%V_{Gr} = \frac{V_{Gr}}{V_{Gr}+V_{Fe}} \times 100\,\%\)

\(\%V_{Gr} = \frac{1}{1+\frac{V_{Gr}}{V_{Fe}} }\times 100\,\%\)

Where:

\(V_{Gr}\) - Volume occupied by the graphite phase, measured in cubic centimeters.

\(V_{Fe}\) - Volume occupied by the ferrite phase, measured in cubic centimeters.

The volume of each phase can be calculated in terms of its density and mass. That is:

\(V_{Gr} = \frac{m_{Gr}}{\rho_{Gr}}\)

\(V_{Fe} = \frac{m_{Fe}}{\rho_{Fe}}\)

Where:

\(m_{Gr}\), \(m_{Fe}\) - Masses of the graphite and ferrite phases, measured in grams.

\(\rho_{Gr}\), \(\rho_{Fe}\) - Densities of the graphite and ferrite phases, measured in grams per cubic centimeter.

Let substitute each volume in the definition of the volume percent of graphite:

\(\%V_{Gr} = \frac{1}{1 +\frac{\frac{m_{Gr}}{\rho_{Gr}} }{\frac{m_{Fe}}{\rho_{Fe}} } } \times 100\,\%\)

\(\%V_{Gr} = \frac{1}{1+\left(\frac{m_{Gr}}{m_{Fe}} \right)\cdot \left(\frac{\rho_{Fe}}{\rho_{Gr}} \right)}\times 100\,\%\)

Let suppose that 100 grams of cast iron are available, masses of each phase are now determined:

\(m_{Gr} = \frac{2.5}{100}\times (100\,g)\)

\(m_{Gr} = 2.5\,g\)

\(m_{Fe} = 100\,g - 2.5\,g\)

\(m_{Fe} = 97.5\,g\)

If \(m_{Gr} = 2.5\,g\), \(m_{Fe} = 97.5\,g\), \(\rho_{Fe} = 7.9\,\frac{g}{cm^{3}}\) and \(\rho_{Gr} = 2.3\,\frac{g}{cm^{3}}\), the volume percent of graphite is:

\(\%V_{Gr} = \frac{1}{1+\left(\frac{2.5\,gr}{97.5\,gr} \right)\cdot \left(\frac{7.9\,\frac{g}{cm^{3}} }{2.3\,\frac{g}{cm^{3}} } \right)} \times 100\,\%\)

\(\% V_{Gr} = 91.906\,\%\)

The volume percent of graphite is 91.906 per cent.

The estimated mass release rate of sulfur dioxide from the stack is [insert value] g/s. The maximum sulfur dioxide concentration on the ground is expected to be [insert value] g/m^3, and its location downwind from the stack is [insert distance].

To estimate the mass release rate of sulfur dioxide from the stack, we need to consider the concentration measured at a specific distance downwind from the stack and the wind speed. In this case, the concentration of sulfur dioxide measured at a distance of 200m downwind is 5.0 x 10^-5 g/m^3. To calculate the mass release rate, we can use the formula:

Mass release rate = Concentration x Cross-sectional area x Wind speed

The effective stack height of the trash incinerator is given as 100m, and we can assume a circular cross-section for the stack. By substituting the given values, we can calculate the mass release rate.

To estimate the maximum sulfur dioxide concentration on the ground, we need to consider the dispersion of pollutants in the atmosphere. The concentration of pollutants decreases as the distance from the source increases. The maximum concentration is usually expected to occur near the source and decreases with distance.

The exact calculation for the maximum concentration and its location downwind from the stack involves complex atmospheric dispersion models. These models consider various factors such as wind speed, atmospheric stability, and topography. Without additional information, it is challenging to provide an accurate estimation of the maximum concentration and its location in this scenario.

maximum temperature ( T₃ ) = 1410 K

Assuming :

constant specific heat and efficiency of 100%

For air :

Cp = 1.005 kJ/kg.k,  Cv = 0.718 kJ/kg.k,  v = 1.4

Given that efficiency for compressor and turbine is 100% the process ( 1-2 , 3 - 4 ) will all be isentropic

We will Apply the formula below

\(\frac{T_{2} }{T_{1} } = ( \frac{p_{2} }{p_{1} } )^{\frac{v-1}{v} } = ( \frac{V_{1} }{V_{2} } )^{v-1}\)

Insert values into equation ( 1 )

T₂ = 551.147 K  ( temperature at compressor exit )

Next : Determine the value of the temperature at Turbine exit ( T₄ )

T₃ / T₄ = 10.7^\(^{\frac{1.4-1}{1.4} }\)

Therefore : T₄ = 1410 / 10.7^0.286

                        = 1410 / 1.93

The centroid of an area can be determined by using the formulas for the x-coordinate and y-coordinate of the centroid. Thus, the centroid of the given area is (a^3/6, m*a^3/6).

How to determine the centroid of the area shown by direct integration?

The centroid of an area can be found by using the following formulas for the centroid's x and y coordinates:

x-coordinate of centroid = (1/A) * ∫xdy

y-coordinate of centroid = (1/A) * ∫ydx

where A is the area of the region, and the integrals are taken over the limits of the area.

Given the equations y = mx and y = kx^2, we can find the x-coordinate and y-coordinate of the centroid as follows:

x-coordinate of centroid = (1/2a) * ∫x*(kx^2) dx from x = 0 to x = a

x-coordinate of centroid = (1/2a) * (1/3) * ∫x^3 dx from x = 0 to x = a

x-coordinate of centroid = (1/2a) * (1/3) * ((a^4)/4)

x-coordinate of centroid = (1/6) * a^3

y-coordinate of centroid = (1/2a) * ∫(mx)*(kx^2) dx from x = 0 to x = a

y-coordinate of centroid = (1/2a) * (m/3) * ∫x^3 dx from x = 0 to x = a

y-coordinate of centroid = (1/2a) * (m/3) * ((a^4)/4)

y-coordinate of centroid = (m/6) * a^3

So, the centroid of the area is (a^3/6, m*a^3/6).

The peak voltage of a sine wave is calculated as the RMS voltage multiplied by the square root of 2. Therefore, the peak voltage of a 240 VRMS sine wave is approximately 340 volts. So, your answer is option 2, 340v.

The RMS voltage (VRMS) of a sine wave is the "root-mean-square" average value of the waveform. It is calculated by taking the square root of the mean of the squares of the instantaneous voltage values over one cycle of the waveform.

For a sine wave, the peak voltage (Vp) is the highest voltage value that the waveform reaches, and it occurs at 90 degrees or pi/2 radians (a quarter cycle) after the zero crossing.

The relationship between VRMS and Vp for a sine wave is given by the formula:

Vp = VRMS x sqrt(2)

This formula shows that the peak voltage of a sine wave is equal to the RMS voltage multiplied by the square root of 2.

Therefore, in the case of a 240 VRMS sine wave, the peak voltage would be:

Vp = VRMS x sqrt(2) = 240 x 1.414 = 339.36 volts

Rounding this to the nearest whole number, we get the answer of 340 volts, which is option 2.
