Question: What is the shear stress formula in a beam?

Options:

1. Shear Stress = V / A
2. Shear Stress = A / V
3. Shear Stress = V * A
4. Shear Stress = V + A

Correct Answer: Shear Stress = V / A

Solution:

Shear stress is defined as the internal force (shear force V) divided by the area (A) over which it acts, hence Shear Stress = V / A.
