Since no figure was given I solved a problem that was similar to the one you described that I worked in my mechanics of materials class. The method should be very similar for your figure. See attached image for my work.

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

The environmental event that significantly increased the visibility of industrial transportation safety is Exxon Valdez Accident.

Exxon Valdez oil leaked into Alaska's Prince William Sound on March 24, 1989. At Prince William Sound, at 12:04 in the morning, the Exxon Valdez, an oil supertanker owned by Exxon Shipping Company and bound for Long Beach, California, collided with the Bligh Reef, 1.5 miles west of Tatitlek, Alaska. Over the course of the following few days, 10.8 million US gallons of crude oil were spilled. After the Deepwater Horizon oil disaster in 2010, the Exxon Valdez oil spill ranks second in terms of oil released in U.S. waters. Prince William Sound is a remote area that can only be reached by boat, helicopter, or airplane, which complicated government and industry response operations and made it particularly challenging to put current response plans into action. Salmon, sea otters, seals, and seabirds all call this area home. A total of 1,300 miles of shoreline were eventually impacted by the oil from the Prudhoe Bay Oil Field, of which 200 miles were significantly or moderately oiled.

Explanation:

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

Answer:

The volume percentage of graphite is 10.197 per cent.

Explanation:

The volume percent of graphite is the ratio of the volume occupied by the graphite phase to the volume occupied by the graphite and ferrite phases. The weight percent in the cast iron is 3.2 wt% (graphite) and 96.8 wt% (ferrite). The volume percentage of graphite is:

\(\%V_{gr} = \frac{V_{gr}}{V_{gr}+V_{fe}} \times 100\,\%\)

Where:

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

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

The expression is expanded by using the definition of density and subsequently simplified:

\(\%V_{gr} = \frac{\frac{m_{gr}}{\rho_{gr}} }{\frac{m_{gr}}{\rho_{gr}}+\frac{m_{fe}}{\rho_{fe}}}\times 100\,\%\)

Where:

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

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

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

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

If \(\rho_{gr} = 2.3\,\frac{g}{cm^{3}}\), \(\rho_{fe} = 7.9\,\frac{g}{cm^{3}}\), \(m_{gr} = 3.2\,g\) and \(m_{fe} = 96.8\,g\), the volume percentage of graphite is:

\(\%V_{gr} = \frac{1}{1+\left(\frac{2.3\,\frac{g}{cm^{3}} }{7.9\,\frac{g}{cm^{3}} } \right)\cdot \left(\frac{96.8\,g}{3.2\,g} \right)} \times 100\,\%\)

\(\%V_{gr} = 10.197\,\%V\)

The volume percentage of graphite is 10.197 per cent.

Following are the solution to the given points:

\(\to C_{Gr} = 100\\\\ \to C_{\alpha}= 0\)From \(Fe-F_{\frac{e}{3}} c\) diagram.  

\(\to W_{\alpha} =\frac{C_{Gr}-C_{o}}{C_{Gr}-C_{\alpha}}\)

           \(= \frac{100-3.6}{100-0} \\\\= \frac{100-3.6}{100} \\\\= \frac{96.4}{100} \\\\=0.964\)

Calculating the weight fraction of graphite:  

\(\to W_{Gr}=\frac{C_0 - c_d}{C_{Gr} -c_d}\)

            \(= \frac{3.6-0}{100-0} \\\\ = \frac{3.6}{100} \\\\= 0.036\)

Calculating the volume percent of graphite:

\(\to V_{Gr}=\frac{\frac{W_{Gr}}{P_{Gr}}}{\frac{w_{\alpha}}{P_{\alpha}}+ \frac{W_{Gr}}{P_{Gr}}}\)

           \(=\frac{\frac{0.036}{2.3}}{\frac{0.964}{7.9}+\frac{0.036}{2.3}}\\\\=0.11368 \times 100\%\\\\=11.368\%\)

Therefore, the final answer is "0.964, 0.036, and 11.368%"

b. The demerits of classical probability are:

1. Classical probability can only be used with events that have definite numbers of possible outcomes.  

2. Classical probability can only handle events where each outcome is equally likely.

3. Classical probability is based on the assumption of linear relationship (which is not always true in real life) between the latent variable and observed scores.

Explanation:

a) Number of judges = 11

Number of judges in favor of FA film = 6

Number of judges in favor of FB film = 5

Probability of judges in favor of FA film = 6/11

Probability of judges in favor of FB film = 5/11

Random sample of judges = 5

Probability that out of five judges, three are in favor of film FA = 3/5 * 6/11

        P₁ = 3 atm (1 10⁵ Pa / 1 atm) = 3 10⁵ Pa

        P₂ = 2.2 atm (1 10⁵ / 1 atm) = 2.2 10⁵ Pa

        PM = 15.9 g / mol (1 kg / 1000 g) = 15.9 10⁻⁻³ kg / mol

        V = 60 gallon (1 m³ / 264.172 gal) = 0.2271 m³

         T = 20 + 273.15 = 293.15 K

Ideal gases are gases that have no interactions between them, so they can be described by the equation

          PV = n R T

Where P is the pressure, V the volume, n the number of moles, R the ideal gas constant (R = 8.314 \(\frac{J}{mol \ K}\)) and T the temperature.

Let's look for the initial moles, that is, on Earth

          n = \(\frac{PV}{RT}\)

          n = \(\frac{3 \ 10^5 \ 0.2271 }{ 8.314 \ 293.15}\)

          n = 27.95 mol

Let's write the ideal gas equation for the two instants let's use subscript 1 for Earth and subscript 2 when the spacecraft is on Tuesday

            P₁ V = n₁ R T

             P₂ V = n₂ R T

            \(\frac{P_1}{n_1} = \frac{P_2}{n_2}\)

            n₂ = \(\frac{P_2}{P_1} \ n_1\)  

            n₂ = \(\frac{2.2 \ 10^5 }{ 3 \ 10^5} \ 27.95\)

            n₂ = 20.95 mol

This is the amount of moles left, the moles lost are

           n_ {lost} = n₁ -n₂

           n_ {lost} = 27.95 - 20.95

The estimated cost to build the new wastewater treatment plant in Seattle, WA is approximately $7,908,474.

When calculating the cost estimate, we take into account the cost index, which measures the relative cost of construction materials and labor at different points in time. In 1992, the cost index for building a wastewater treatment plant was 59, and it has increased to 98 in the present day.

To calculate the estimated cost, we use the formula:

Estimated Cost = (Historical Cost) x (Cost Index at Present) / (Cost Index in the Past)

Plugging in the values, we get:

Estimated Cost = ($4,750,000) x (98) / (59)

              = $7,908,474

Resilience engineering is about developing adaptable systems that can handle unexpected situations and are able to cope with the effects of adverse external events that might cause system failure. As a software engineer, you need to inform system developers about the following four characteristics that reflect the resilience of an organization, as described by Hollnagel (2010):Maintainability: This characteristic reflects the degree to which a system can be maintained or repaired after it has been damaged. In other words, it assesses the system's ability to remain in good working order or quickly recover from damage. An example of maintainability would be the ability to quickly repair an engine that has been damaged during an accident.Flexibility: This characteristic reflects the degree to which a system can be modified or adapted to cope with changing circumstances. Flexibility is essential for resilience because it enables a system to respond to new challenges and adapt to different circumstances. An example of flexibility would be the ability to change the specifications of a car to adapt to different driving conditions.Redundancy: This characteristic reflects the degree to which a system can continue to function even if some of its components fail. Redundancy is important because it ensures that the system can continue to operate even if one or more components are not working properly. An example of redundancy would be having a backup generator in case the primary generator fails.Responsiveness: This characteristic reflects the degree to which a system can respond to changing circumstances or threats. Responsiveness is important because it enables a system to quickly and effectively respond to unexpected events.
