The function that causes values of both x and to develop the highest feasible moment at A according to the provided suspended mass is written as 14715 Nm (clockwise).

The quantity of matter or substance that makes up a thing is known as its mass. The unit of measurement is the kilogramme, abbreviated as kg. It's crucial to keep in mind that mass differs from weight. While weight varies with changes in gravity, mass never changes.

We have identified the following values,

adjust for any angle 00 ≤ θ ≤ 900 any extension 0 ≤ x ≤ 5 m.

So,

Let us consider an equation to calculate the moment using θ and x as variables around point A.

⇒ ((9−1.5) + x) (cosθ) (120) (9.81)

When we are simplifying the given equation gives us:

⇒ MA ​= (7.5+x) 1177.2 cosθ

Here the maximum moment will develop if θ = 0 and x=5 m.

Then, by substituting these values gives us:

⇒ MA​=(7.5+x)1177.2cosθ

⇒ MA​=(7.5+5)1177.2cos00

Thus, the value of MA is written as, 14715 Nm (clockwise)

A geotechnical investigation is an assessment of the physical and chemical properties of soil, rock, and other subsurface materials. It is typically carried out in order to evaluate the suitability of the ground for a particular purpose, such as the construction of a building or bridge.

Site investigation is the process of collecting and evaluating data about the soil, rock, and groundwater conditions at a particular location. This is usually done before designing concrete foundations, as the characteristics of the subsurface materials can have a significant impact on the stability and integrity of the foundation.

A geotechnical report is a document that summarizes the results of a geotechnical investigation. It typically includes information about the geology of the site, the properties of the subsurface materials, and any potential geotechnical hazards or issues that may affect the proposed development. The report may also include recommendations for how to address any issues that are identified, such as installing foundation reinforcement or providing additional support for the structure.

Site investigations typically involve a number of different techniques, such as soil and rock sampling, borehole drilling, and laboratory testing. The specific techniques used will depend on the nature of the project and the type of information that is needed.

The pressure of seawater will be 2.14*107 N/m2 and the density will be 8.53*103 kg/m3.

Pressure is a type of force applied to an object by another object over a surface area. Pressure is measured in units of force per unit area and is usually expressed in terms of pascals (Pa).

The bulk modulus of elasticity, K, is a measure of the stiffness of a material and is defined as the ratio of bulk stress to the resulting strain. In this problem, we need to calculate the density and pressure at a depth of 2500 m, based on the given bulk modulus and 98 kPa pressure at the surface.
To solve this problem, we will use the equation K = -dp/dρ, where dp is the change in pressure with depth and dρ is the change in density with depth. Since we are given the bulk modulus and pressure on the surface, we can calculate the change in density with depth as follows:
dρ = -K*dp/dz
where dp = rgdz and rg is the gravity of the Earth. Substituting these values, we get:
dρ = -2.34*109*98*103/(9.8*2500) = -7.78*103 kg/m3
This means that for every metre of depth, the density of seawater decreases by 7.78*103 kg/m3. Therefore, at a depth of 2500 m, the density of seawater will be:
ρ = 1030 - 7.78*103*2500 = 8.53*103 kg/m3
Similarly, we can calculate the pressure at a depth of 2500 m using the equation P = P0 + rgdz, where P0 is the pressure at the surface. Substituting the values, we get:
P = 98*103 + 9.8*2500*8.53*103 = 2.14*107 N/m2
Therefore, at a depth of 2500 m, the pressure of seawater will be 2.14*107 N/m2 and the density will be 8.53*103 kg/m3.

a) The power transmitted by the belt, is 5.53 hp and (b) the work done in one minute of sanding, in Btu is 37500 Btu.

What is power?
Power is the ability to influence people, events, and outcomes. It is a fundamental element in the human experience, and it has been studied by scholars and philosophers for centuries. Power can manifest itself in many forms, such as political, economic, military, cultural, or social. It is often used to control or dominate others, and it is used to create and maintain systems of inequality and oppression. Power can also be used for good, such as providing people with the resources and ability to make positive changes in their lives and the world around them.

a) Power Transmitted by the Belt = (15 bf) x (1500 ft/min) x (0.2) = 4500 bf-ft/min = 4500 ft-lb/min = 7500 Btu/s = 5.53 hp

A stall happens when the smooth airflow over the unmanned airplane`s wing is disrupted, and the lift degenerates rapidly. This is caused when the wing "exceeds its critical angle of attack."

The angle of attack refers to the angle at which the airplane's wing meets the air that is flowing over it. When an airplane actually is taking off, it is lifting the nose up into the air. And, if that nose continues to rise ultimately it reaches a point where the air is not able to smoothly flow over the wing, causing the airplane to drop. And, this is the point when the airplane exceeds its critical angle of attack.

Exceeding the critical angle of attack is known to be a stall. This has no concern with the engine stalling, it just concerns with the wings not producing enough lift to keep the airplane in the air.

The size of the THHN feeder conductor required for two 230 VAC, 7.5 HP motors, one 115 VAC, 1.5 HP short time motor and one 230 VAC, 0.75 HP motor is 3 AWG.

To calculate the size of the THHN feeder conductor, we first need to calculate the total load current for all the motors. To do that, we will use the following formula: I = (HP x 745.7) / (V x 1.73).

For the two 7.5 HP motors, the total load current is (7.5 x 745.7) / (230 x 1.73) = 29.7 A. For the 1.5 HP short-time motor, the total load current is (1.5 x 745.7) / (115 x 1.73) = 8.85 A. For the 0.75 HP motor, the total load current is (0.75 x 745.7) / (230 x 1.73) = 4.41 A.

Adding all the load currents yields a total load current of 42.96 A. Then we can refer to the NEC Table 310.15(B)(16) to determine the minimum THHN feeder conductor size. At 42.96 A, the minimum THHN feeder conductor size is 3 AW.

The pavement will last between 41 and 50 years with a reliability of 90%.

A road surface, also known as pavement, is a durable surface material that is laid down on an area intended to support vehicular or pedestrian traffic, such as a road or walkway.

First, calculate the number of equivalent single axle loads (ESALS):

ESALS = 600*30 + 1400*20 = 55600.

Next, calculate the design life (L) using the formula: L =

(ESALS/18000)^(1/TSI) * (Ec/PSI)^(-1/2*SD).

Plugging in the values,

L = (55600/18000)^(1/2.5) * (5.5 x 10^6/4.5)^(-1/0.7) = 41.8.

Lastly, calculate the reliability (R) using the formula:
