Question: What is the effect of increasing the moment of inertia on the bending stress in a beam?

Options:

1. Bending stress increases
2. Bending stress decreases
3. Bending stress remains the same
4. Bending stress becomes zero

Correct Answer: Bending stress decreases

Solution:

Increasing the moment of inertia decreases the bending stress in a beam for a given bending moment.
