. Determine the state of stress at point A on the cross-section at section a-a of the cantilever beam. Show the results in a differential element at the point.

To calculate the open-circuit secondary voltage of the given distribution transformer, we can use the voltage ratio and the referred magnetizing reactance.

The voltage ratio of the transformer is 2400 V / 240 V = 10. This means that the primary voltage is 10 times the secondary voltage.iven that the magnetizing breferred to the high-voltage side is 5100 ohms, we can calculate the referred leakage reactance for the primary side.

The referred leakage reactance for the primary side is equal to the leakage reactance referred to the high-voltage side divided by the square of the voltage ratio:Referred primary leakage reactance = (5 ohms) / (10^2) = 0.05 ohms.In an open-circuit condition, the current is negligible. Therefore, the voltage drop across the referred primary leakage reactance is also negligible. Thus, the open-circuit secondary voltage is equal to the rated high-voltage applied to the high-voltage winding, which is 2400 V.

Note that when the controller's output is set by a constant plus the error multiplied by the gain, you have "proportional Control" (Option A)

Proportional control is a type of control system in which the output of the controller is determined by a constant value (offset) plus the error multiplied by the gain.

The gain is a coefficient that defines how strongly the control system reacts to a mistake. This control is often employed in industrial processes and feedback control systems where precise control of a process variable is required. The controller's output is directly proportional to the error, thus the term proportional control.

a. True .In a scroll compressor, refrigerant vapor is indeed compressed between two spinning scrolls. These scrolls have spiral or involute shapes and fit together in a way that creates moving pockets or chambers of decreasing volume.

This compression process is continuous and results in a smooth, pulsation-free flow of compressed refrigerant. The design of the scroll compressor reduces leakage and provides efficient compression. As the scrolls rotate, the refrigerant vapor is trapped and compressed, leading to an increase in pressure and temperature. Its design makes it suitable for applications that require a steady flow of compressed refrigerant. The scrolls do not touch each other directly, but rather create a series of crescent-shaped gas pockets that move towards the center of the compressor. The scroll compressor is commonly used in HVAC systems and refrigeration applications due to its compact size, quiet operation, and high energy efficiency.

The statement that refrigerant vapor is compressed between two spinning scrolls in a scroll compressor is true.

A large tower is to be supported by a series of steel wires. It is estimated that the load on each wire will be 11,100 N.

Determine the minimum required wire radius assuming a factor of safety of 3 and a yield strength of 1500 MPa.

answer in mm please

Answer:

the minimum required wire radius is 5.3166 mm

Explanation:

Given that;

Load F = 11100N

N = 3

∝y = 1500 MPa

∝workmg = ∝y / N = 1500 / 3 = 500 MPa

now stress of Wire:

∝w = F/A

500 × 10⁶ = 11100 / A

A = 22.2 × 10⁻⁶ m²

so

(π/4)d² = A

(π/4)d² = 22.2 × 10⁻⁶

d² = 2.8265 × 10⁻⁵

d = 5.3165 7 × 10⁻³ m³

now we convert to mm(millimeters)

d = 5.3166 mm

Answer:

  (x, y) = (5.76, 1 5/7)

Explanation:

The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.

For the moment about the y-axis, we can define a differential of area as ...

  dA = (y2 -y1)dx

where y2 = √(x/k2) and y1 = k1·x^3

The distance of that area from the y-axis is simply x.

So, the x-coordinate of the centroid is ...

  \(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)

For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...

  \(a_x=115.2\\a=20\\c_x=5.76\)

The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...

  \(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)

The centroid of the shaded area is ...

  (x, y) = (5.76, 1 5/7)

The elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

Elevation of High Point = 1350.0 ft

Elevation of PVT = 1325.0 ft

Elevation of PVC = 1345.0 ft

A 520-ft-long equal-tangent crest vertical curve connects tangents that intersect at station 340 + 00 and elevation 1325 ft. The initial grade is +4.0% and the final grade is 2.5%.

Determine the elevation and stationing of the high point, PVC, and PVT. A vertical curve is used to connect two tangents that have differing slope grades, and it is the arc of a parabola. The parabolic arc's vertex is referred to as the high point of the curve.

PVC (point of vertical curvature) is the point where the parabolic arc starts and the tangent line ends, and PVT (point of vertical tangency) is the point where the parabolic arc ends and the tangent line begins.

Therefore, by considering the given data, we can calculate the elevation and stationing of the high point, PVC, and PVT of the vertical curve in the following way;

Stationing of the curve = 340+00. High point of the curve = L/2 + 340+00 = 520/2 + 340+00 = 342+60PVC = 340+00. Elevation of PVC = Elevation of point of intersection + (Initial grade / 100) x Length of the curve 1325 + (4/100) x 520 = 1345 ft.

Elevation of PVT = Elevation of point of intersection + (Final grade / 100) x Length of the curve 1325 + (2.5/100) x 520 = 1350 ft.

Therefore, the elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

Elevation of High Point = 1350.0 ft

Elevation of PVT = 1325.0 ft

Elevation of PVC = 1345.0 ft

Answer:

\(\triangle h=4.935m\)

Explanation:

From the question we are told that:

Liquid density \(\rho=800\)

Diameter of pipe \(d=4cm \approx 0.004m\)

Diameter of venture \(d=10cm \approx 0.010m\)

Specific weight of mercury P_mg \(133 kN/m^3\)

Flow rate \(r=0.05 m^3/s\)

Area A:

            \(A_1=\frac{\pi}{4}0.1^2\\A_1=0.00785m^2\\A_2=\frac{\pi}{4}0.04^2\\A_2=0.001256m^2\\\)

Generally the Bernoulli's equation is mathematically given by

\(\frac{P_1}{\rho_1g}+\frac{V_1^2}{2g}=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}\\\)

Where

\(V_1=\frac{r}{A_1} \\\\ &V_1=\frac{r}{A_2}\)

Therefore

\(P_1-P_2=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

Generally the equation for pressure difference b/w manometer fluid is given as

\(P_1-P_2=(p_mg-pg)\triangle h\)

Therefore

\((p_mg-pg)\triangle h=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

\(\triangle h=\frac{\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})}{(p_mg-pg)}\)

\(\triangle h=\frac{\frac{(800)(0.05)^2}{2}(\frac{(0.1)^2-(0.4)^2}{(0.1)^2(0.04)^2})}{(1.33*10^3-800*9.81)}\)

\(\triangle h=4.935m\)

Therefore elevation change is mathematically given by

\(\triangle h=4.935m\)

Power screw applications use common thread forms like square, Acme, and buttress threads.

Square threads are high efficiency but prone to wear, while Acme threads offer better wear resistance.

Buttress threads provide high load capacity and efficient operation in one direction. Brakes and clutches function differently, with brakes slowing down or stopping system rotation and converting kinetic energy into heat energy.

Different types of gears, such as spur gears, helical gears, bevel gears, worm gears, and planetary gears, are used to ensure smooth power transmission.

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.
