Question: What is the moment of inertia (I) for a rectangular beam section with width (b) and height (h)?

Options:

1. (b * h^3) / 12
2. (b * h^2) / 12
3. (b * h^3) / 3
4. (b * h) / 12

Correct Answer: (b * h^3) / 12

Solution:

The moment of inertia (I) for a rectangular beam section is given by I = (b * h^3) / 12, where b is the width and h is the height of the section.
