Answer:

To determine the maximum deflection in region AB of the overhang beam, we can use the following equation:

δmax = (5wL^4)/(384EI)

where δmax is the maximum deflection, w is the distributed load, L is the length of the beam, E is the modulus of elasticity, I is the moment of inertia, and I is the distance from the fixed end to the point of maximum deflection.

In this case, the beam is fixed at one end and has an overhang at the other end, so we need to consider two separate regions: the region from the fixed end to the end of the overhang (region AB), and the region from the end of the overhang to the free end (region BC).

For region AB, the length of the beam is L = 10 ft, the modulus of elasticity is E = 29(10^3) ksi, the moment of inertia is I = 204 in^4, and the distance from the fixed end to the end of the overhang is x = 6 ft. We also need to find the distributed load w that produces the maximum deflection.

To find w, we can use the fact that the total load on the beam is equal to the weight of the beam itself plus any additional loads. Let's assume that the beam has a weight of 100 lb/ft and that there is a concentrated load of 500 lb at the end of the overhang. Then the total load on the beam is:

wtotal = wbeam + wload = (100 lb/ft)(10 ft) + 500 lb = 1500 lb

The distributed load is then:

w = wtotal/L = 1500 lb/10 ft = 150 lb/ft

Now we can plug in the values and solve for δmax:

δmax = (5wL^4)/(384EI) = (5)(150 lb/ft)(10 ft)^4 / (384)(204 in^4)(29(10^3) ksi)

δmax = 0.256 in

Therefore, the maximum deflection in region AB of the overhang beam is 0.256 inches.

When the steam has reached a temperature of 212⁰F, its psig is 0 psig.

At this temperature, the steam is at its boiling point and any additional heat energy added will cause it to convert into water vapor. The pressure exerted by the steam at this point is equal to the atmospheric pressure, which is 0 psig at sea level.

psig (pounds per square inch gauge) can be determined using the following:

1. Convert the temperature from Fahrenheit to Celsius:
  (212°F - 32) x 5/9 = 100°C

2. Determine the saturation pressure of steam at this temperature. At 100°C, the saturation pressure of water is approximately 14.7 psi (pounds per square inch) in absolute terms (psia).

3. Convert this pressure to psig:
  psig = psia - atmospheric pressure
  In this case, atmospheric pressure is generally assumed to be 14.7 psi, so:
  psig = 14.7 psi - 14.7 psi = 0 psig

So, when steam has reached a temperature of 212⁰ Fahrenheit, its psig is approximately 0 psig.

When it comes to sorting algorithms, there are various methods available, and each has its own strengths and weaknesses. Two popular algorithms are mergesort and insertion sort. In this context, the question is which algorithm is better for sorting long lists.

Out of the given options, option III, which states that mergesort runs faster than insertion sort, is a valid reason why mergesort is a better sorting algorithm for long lists. Mergesort is a divide-and-conquer algorithm that recursively splits the input list into smaller sub-lists and then merges them in a sorted order. This approach leads to a runtime of O(nlogn), which is faster than insertion sort's runtime of O(n^2) for larger lists.

On the other hand, options I and II are not valid reasons for choosing mergesort over insertion sort for sorting long lists. Mergesort requires more code and storage space compared to insertion sort. However, for long lists, runtime is usually the most critical factor, making mergesort a more suitable option.

In conclusion, mergesort is a better sorting algorithm than insertion sort for long lists because it has a faster runtime of O(nlogn), compared to insertion sort's slower O(n^2) runtime.

The average velocity of air in the 3-in-diameter pipe supplying 3 ft3/s of air is approximately 61.22 ft/s.

To find the average velocity of air in the 3-in-diameter pipe supplying 3 ft3/s of air, we can use the formula:

velocity = flow rate / cross-sectional area

The cross-sectional area of a 3-in-diameter pipe is πr^2, where r is the radius (which is half of the diameter). So for a 3-in-diameter pipe, the radius is 1.5 in, or 0.125 ft.

π(0.125)^2 = 0.049 ft^2 (rounded to three decimal places)

Plugging in the given flow rate of 3 ft3/s, we get:

velocity = 3 / 0.049

velocity ≈ 61.22 ft/s

The value of C is 7.85 pF if the energy stored in the capacitor equals the energy stored in the inductor.

The energy stored in the capacitor is given by:

E_c = (1/2)C(V²)

The energy stored in the inductor is given by:

E_l = (1/2)L(I²)

At resonance, the current through the inductor is maximum and the voltage across the capacitor is maximum. Therefore, the energies stored in the capacitor and inductor are equal.

Set these two equations equal to each other and solve for C:

(1/2)C(V²) = (1/2)L(I²)

At resonance:

w = 1/√(LC)

I = V/(√(Ry² + (wL - 1/(wC))²))

Substituting these values and simplifying:

C = 1/(4π²f² × L)

where f = resonant frequency in Hz.

Since the inductor has a resonant frequency of 300 Hz, calculate C:

This means that the pressure at the given point on the airfoil is 26% lower than the freestream pressure. This corresponds to a suction force on the airfoil, which contributes to the lift generated by the airfoil.

The pressure coefficient (Cp) is a dimensionless quantity used in aerodynamics to describe the pressure distribution over a body. It is defined as the difference between the local pressure and the freestream pressure, divided by the dynamic pressure of the freestream flow. The dynamic pressure is defined as 1/2 times the density of the freestream flow times the freestream velocity squared.

To calculate the pressure coefficient at a given point on the airfoil, we need to know the local pressure, the freestream pressure, and the freestream velocity. Given that the freestream is at Mach 0.54 and the local Mach number is 0.9, we can use the isentropic relations for an ideal gas to find the corresponding static pressure ratio.

The isentropic relations for an ideal gas relate the static pressure, temperature, and density to the Mach number and the ratio of specific heats (gamma). For air, gamma is approximately 1.4. Using these relations, we can find the static pressure ratio as follows:

P/Po = (1 + (gamma-1)/2*Mach^2)^(gamma/(gamma-1))

where P is the local static pressure, Po is the freestream static pressure, Mach is the local Mach number, and gamma is the ratio of specific heats.

Substituting the given values, we get:

P/Po = (1 + (1.4-1)/2*0.9^2)^(1.4/(1.4-1))

= 1.221

Therefore, the pressure coefficient at the given point on the airfoil is:

Cp = (P - Po) / (1/2 * rho * V^2)

where rho is the density of the freestream flow and V is the freestream velocity. Since the freestream Mach number is given, we can use the isentropic relations again to find the freestream density and velocity. For simplicity, we assume that the flow is incompressible (Mach number << 1), so that the density and velocity are constant.

Assuming standard sea-level conditions (rho = 1.225 kg/m^3), we get:

V = Mach * sqrt(gammaRT)

= 0.54 * sqrt(1.4287288.15)

= 319.9 m/s

where R is the gas constant for air, and T is the absolute temperature in Kelvin.

Therefore, the pressure coefficient is:

Cp = (P - Po) / (1/2 * rho * V^2)

= (1.221 - 1) / (1/2 * 1.225 * 319.9^2)

= 0.260
