Answer:
p=15.097lbf/in^2
Explanation:
the manometric pressure is that in which the atmospheric pressure is not taken into account, so for this case only the pressure exerted by the water on the bus is calculated using the following equation.
P=ρgh
where
ρ=density of water at 55°F=999.4kg/m^3
g=9.81m/s^2
h=35ft=10.668m
Solving
P=(994.4)(9.81)(10.668)=104067.02Pa = 15.097lbf/in^2
the gage pressure does a skin diver experience when they dive to 35 ft is 15.097lbf/in^2

Explanation: three phase induction
Answer:
Explanation:
Diagrams of Shear force show the total shear force at each cross section of a structural member throughout the length of the beam or structural member. However, that force is not equally distributed throughout the individual cross section of the structural member. The maximum shear stress is referred to as the maximum concentrated shear force in a small area.
The Maximum Shear Stress theory states that failure occurs when the
maximum shear stress from the total of principal stresses equals
or exceeds the value obtained for the shear stress at yielding in the
uniaxial tensile test.
At yielding, in an uni-axial test, the principal stresses is given as:
σ=Sy; -
σ2 = 0 and σ3 = 0.
Therefore the shear strength at yielding
Ssy =[σ- (σ2 or σ3=0)]/2. Therefore Ssy = Sy/2
From the information given:
Tmax= σ1 - σ2/2
Tmax= 450-200/2
Tmax= 250/2
Tmax= 125 kpa
