Damage reports should contain the information needed for what?
Answer:
it's damage kindly be carefulDuring the design of spherical pressure vessel for space programs, a primary criterion is the mass of the vessel (which determines how much it costs to put it into the orbit). Given the stress in a thin walled spherical vessel is tensile and given by:
Tensile stress in a thin wall spherical shell is given by
σ = ( p r ) /2t
Tensile stressThis is the type of stress that involves pulling out. it is the opposite of compressive stress.
The tensile stress, σ at the circumference of the shell is the hoop stress. The value equals that of pressure acting on the area.
Therefore:
σ * 2πr * t = p * πr^2
where
2πr = circumference of a circle
πr^2 = area of a circle
p = internal pressure
t = thickness
σ * 2πr * t = p * πr^2
σ = ( p r ) /2t

The steel bracket is used to connect the ends of two cables. if the allowable normal stress for the steel is sallow = 30 ksi, determine the largest tensile force p that can be applied to the cables. assume the bracket is a rod having a diameter of 1.5 in.
The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb
The static equilibrium is given as:
F = P (Normal force)
Formula for moment at section
M = P(4 + 1.5/2)
= 4.75p
Solve for the cross sectional area
Area = [tex]\frac{\pi d^{2} }{4}[/tex]
d = 1.5
[tex]\frac{\pi *1.5^{2} }{4}[/tex]
= 1.767 inches²
Solve for inertia
[tex]\frac{\pi *0.75^4}{4}[/tex]
= 0.2485inches⁴
Solve for the tensile force from here
[tex]\frac{F}{A} +\frac{Mc}{I}[/tex]
30x10³ = [tex]\frac{P}{1.767} +\frac{4.75p*0.75}{0.2485} \\\\[/tex]
30000 = 14.902 p

Steering and suspension question
Answer:
I would say only A
Explanation:
steering dampeners are applied to heavy-duty and off-road vehicles in order to help stabilize and balance out your steering in rough terrain. luxury cars won't have them because, well, they are cars, and cars are not used for off-roading. trucks and SUVs and sometimes vans are though, which makes sense more than just a random luxury car with dampeners just sitting there for no reason at all when heavy-duty vehicles need them more than the car.

A glass of water with a mass of 0.45kg at 20∘C is to be cooled to 0∘C by dropping ice cubes at 0∘C into it. The latent heat of fusion of ice is 334kJ/kg, and the specific heat of water is 4.18kJ/kg⋅∘C. The amount of ice that needs to be added is.
By using the concept of heat transfer, we need to add 0.045kg or 45g of ice to the glass of water to cool it from 20∘C to 0∘C.
The heat lost by the water is equal to the heat gained by the ice cubes. We can use the following equation to calculate the heat transfer:
Q = m_w * c_w * ΔT + m_i * L_f
where Q is the heat transfer, m_w is the mass of water, c_w is the specific heat of water, ΔT is the temperature change (20-0 = 20∘C), m_i is the mass of ice, and L_f is the latent heat of fusion of ice.
We know the values of m_w (0.45kg), c_w (4.18kJ/kg⋅∘C), ΔT (20∘C), and L_f (334kJ/kg). We can rearrange the equation to solve for m_i:
m_i = (Q - m_w * c_w * ΔT) / L_f
Substituting the values, we get:
m_i = [(0.45kg) * (4.18kJ/kg⋅∘C) * (20∘C) - 0] / (334kJ/kg
m_i = 0.045kg

Might a synchronous motor equally well be called a synchronous inductor
In Engineering, a synchronous motor is sometimes referred to as synchronous capacitor but not a synchronous inductor.
What is a synchronous motor?A synchronous motor can be defined as an alternating current (AC) electric motor in which the rotation speed of the shaft is directly proportional to the frequency of the supply current, especially at steady state.
Basically, a synchronous motor is sometimes referred to as a synchronous capacitor because it can be used to correct the power factor (PF) of a lagging load such as an induction motor.
However, a synchronous motor cannot be called a synchronous inductor because the rotation speed of the shaft is not proportional to the synchronous speed of the motor. Thus, they are called an synchronous motor.
