Answer:

Draw up the contract for construction management.

Answer:

Work with construction management to solve specific problems as they arise.

Ensure compliance with safety standards.

Explanation:

The results of the calculations are (a) P = 37.97 kN and (b) P = 35.62 kN.

The surface won't be cut if you press the flat section of the knife against the fruit. The force is dispersed over a wide area.

Using the parameters and figure provided in the problem, we have:

A = b*h = 0.14*0.24 = 0.0336 m^2

S = (b*h^2)/6 = (0.14*0.24*0.24)/6 = 0.001344 m^3

q = 5400*0.0336 = 181.44 N/m

(a) The load P at 8.5 MPa = 8.5*106 Pa (allowable bending stress)

σ = M/S

M = *S thus equals 0.001344*8.5*106 = 11424 Nm.

Aside from that

M = (P*L/4) + (q*L^2)/8

11424 = (P*1.2/4) + (181.44*1.2^2)/8

11424 = 0.3*P + 32.6592

P = (11424-32.6592)/0.3 = 37.97 kN

(b) If (allowable shear stress) = 0.8 MPa, then the value of P is equal to 0.8*106 Pa.

(2*A*τ/3) = P/2 + q*L/2

(2*0.0336*0.8*10^6)/3 = P/2 + 181.44*1.2/2

17920 = P/2 + 108.864

P = (17920 - 108.864) * 2 = 35.62 kN.

The distance traveled for a wingtip bearing change of 5 with an elapsed time of 6 minutes and a fuel consumption rate of 12 gallons per hour is 1.2 miles.

Given the information provided, we have a wingtip bearing change of 5 and an elapsed time of 6 minutes between bearing changes.

We also know the rate of fuel consumption is 12 gallons per hour.
To calculate the distance covered, we can use the formula Distance = Speed x Time.

However, we need to convert the elapsed time to hours since the fuel consumption rate is given in gallons per hour.
To convert minutes to hours, we divide the elapsed time of 6 minutes by 60.

This gives us 0.1 hours.
Next, we calculate the distance covered by multiplying the fuel consumption rate of 12 gallons per hour by the elapsed time of 0.1 hours.

This gives us a distance of 1.2 miles.
Therefore, the wingtip bearing change of 5 corresponds to a distance of 1.2 miles traveled.

The time t2 at which 50 percent of the initial energy stored in the capacitance has been dissipated in the resistance can be determined using the formula for energy dissipation in a resistor-capacitor circuit, which is E=½CV²(1-e^(-2t/RC)). Initially, all the energy is stored in the capacitance, and as time passes, this energy is gradually dissipated in the resistor.

When 50 percent of the initial energy has been dissipated, the value of E will be half of the initial energy, which can be substituted in the above formula to solve for t2. Therefore, t2 can be found by setting E=½CV² and solving for t in the equation ½=1-e^(-2t/RC). The time constant RC of the circuit determines the rate of energy dissipation, and therefore, the value of t2. In general, t2 is equal to approximately 0.7 times the time constant RC.

If the oil pressure gauge fluctuates over a wide range from zero to normal operating pressure, the most likely cause is air lock in the scavenge pump intake.

Oil pressure gauge fluctuation is a common problem for the engine. It can occur due to various reasons such as faulty oil pressure gauge, oil pump failure, improper maintenance of the engine, oil leakage, and much more. But if the oil pressure gauge fluctuates over a wide range from zero to normal operating pressure, the most likely cause is air lock in the scavenge pump intake.The scavenge pump in the engine is used to remove the oil from the engine's crankcase and delivers it back to the oil tank. If there is an air lock in the scavenge pump intake, then it will not pump the oil properly from the crankcase and deliver it back to the oil tank. It will cause the oil pressure to fluctuate over a wide range from zero to normal operating pressure.To fix this issue, you should first check the oil level in the engine and make sure that it is at the proper level. After that, you can check the scavenge pump intake for any air lock or blockage. If there is an air lock, then you need to remove it. If there is a blockage, then you need to remove the blockage to get the oil pump working again properly.

The pressure needed at point (1) to produce the flow where water "bubbles up above the exit of the vertical pipe attached to three horizontal pipe segments is 0.750 psi.

The Bernoulli's equation for incompressible fluid can be given as,

\(P_1+\dfrac{1}{2}\rho v_1^2+\rho gh_1=P_2+\dfrac{1}{2}\rho v_2^2+\rho gh_2\)

Here, ρ is density of fluid, g is acceleration due to gravity, (P) is the pressure v is velocity, h is height of elevation and subscript (1 and 2) is used for point 1 and 2.

Water "bubbles up" h2 = 9 in.  Above the exit of the vertical pipe attached to three horizontal pipe segments.

The total length of the 1.75-in.- diameter galvanized iron pipe between point (1) and the exit is 21 inches. h3 = 18 in.

Reynolds number is,

\(R_e=\dfrac{V_3D}{v}\\R_e=\dfrac{4.01\dfrac{0.75}{12}}{1.21\times10^{-15}}\\R_e=2.07\times10^4\)

The formula for the ratio of pressure to radius, when pressure and velocity at point 2 is zero can be given as,

\(\dfrac{p_1}{r}=z_2\left(f\dfrac{l}{d}+\sum k_L\right)\dfrac{v^2}{2g}-\dfrac{v_1^2}{2g}\)

Here, f=0.039 and ∑K(L)=4.5. Put the values,

\(\dfrac{p_1}{r}=\dfrac{7}{12}\left(0.03\dfrac{21}{0.75}+4.5-1\right)\dfrac{4.01^2}{2\times32.2}\\\dfrac{p_1}{r}=1.73\rm\; ft\)

Answer:

Explanation:

Calculate the mean effective pressure of an ideal Otto cycle

Given data:

compression ratio = 9

inlet pressure ( P1 ) = 14 psia

Initial temperature ( T1 ) = 60°F = 520 R

Final/maximum temp ( T3 ) = 1500°F = 1960 R

using the constant specific heats at room temperature

attached below is the detailed solution

The mean effective pressure of the ideal Otto Cycle that uses air as the working fluid is; 31.28 psia

We are given;

Initial pressure; P₁ = 14 psia

Initial temperature; T₁ = 60°F = 520 R

Maximum temperature; T₃ = 1500°F = 1960 R

Compression ratio = 9

From tables, the specific heat capacities and constants are;

c_v = 0.171 btu/lbm.R

c_p = 0.24 btu/lbm.R

R = 0.3704 btu/lbm.R

ratio of specific heats; k = 1.4

Let us first calculate the initial volume from the formula;

V₁ = RT₁/P₁

V₁ = (0.3704 * 520)/14

V₁ = 13.7577 ft³/lb.m

Thus;

V₂ = V₁/9

V₂ = 13.7577/9

V₂ = 1.5286 ft³/lb.m

T₂ = T₁(V₁/V₂)^(k - 1)

T₂ = 520(9)^(1.4 - 1)

T₂ = 1252.277 R

Similarly;

T₄ = T₃/9

T₄ = 1960/(9^(1.4 - 1))

T₄ = 813.87 R

Q_in = c_v(T₃ - T₂)

Q_in = 0.171(1960 - 1252.277)

Q_in = 121.02 btu/lbm

Q_out = c_v(T₄ - T₁)

Q_out = 0.171(813.87 - 520)

Q_out = 50.251 btu/lbm

W_net = Q_in - Q_out

W_net = 121.02 - 50.251

W_net = 70.769 btu/lbm

Formula for the mean effective pressure is;

mean effective pressure = W_net/(V₁ - V₂)

mean effective pressure = 70.769/(13.7577 - 1.5286)

mean effective pressure = 5.7869 btu.ft³

Converting to psia gives;

Mean effective pressure = 31.28 psia

Where No is the number of teeth on the pinion, k is the gear ratio, m is the number of starts on the pinion, V is the pitch line velocity, θ is the pressure angle, and NG is the number of teeth on the gear.
To minimize gearbox size and avoid interference, the number of teeth on the pinion should be kept as low as possible. However, this is limited by the requirement to maintain a reasonable gear ratio and to avoid interference between the teeth.
The pitch line velocity is a function of the operating speed and the pitch diameter of the gears.

The pressure angle is a design parameter that is typically chosen based on the application requirements.
Therefore, the minimum number of teeth for the pinion and gear to minimize gearbox size and avoid interference will depend on the specific application requirements, such as the gear ratio, operating speed, and power transmission requirements.
