Question: What is the formula for calculating the moment of inertia for a rectangular beam?

Options:

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

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

Solution:

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