Answer:
Shear Stress = 0.415 ksi
Step-by-step explanation:
In order to find the shear stress we first need to find the cross sectional area of pin B. The area is given as follows:
A = πd²/4
where,
A = Area of cross section of pin = ?
d = diameter of pin = 0.28 in
Therefore,
A = π(0.28 in)²/4
A = 0.0615 in²
Now, the shear stress is given as:
Shear Stress = Shear Force/Area
Shear Stress = 25.6 lb/0.0615 in²
Shear Stress = 415.8 psi
Shear Stress = 0.415 ksi
