Answer:
E = 8.83 kips
Explanation:
First, we determine the stress on the rod:
where,
σ = stress = ?
F = Force Applied = 1300 lb
A = Cross-sectional Area of rod = 0.5
Therefore,
Now, we determine the strain:
Now, the modulus of elasticity (E) is given as:
<u>E = 8.83 kips</u>
Answer:
Check the explanation
Explanation:
Kindly check the attached image below to see the step by step explanation to the question above.
Answer:
Force per unit plate area is 0.1344
Solution:
As per the question:
The spacing between each wall and the plate, d = 10 mm = 0.01 m
Absolute viscosity of the liquid,
Speed, v = 35 mm/s = 0.035 m/s
Now,
Suppose the drag force that exist between each wall and plate is F and F' respectively:
Net Drag Force = F' + F''
where
= shear stress
A = Cross - sectional Area
Therefore,
Net Drag Force, F =
Also
F =
where
= dynamic coefficient of viscosity
Pressure, P =
Therefore,
