The moment of inertia (I) is a physical property of a structural member that describes its resistance to bending. It is calculated using the following formula:
I = (bh^3)/12
where b is the width of the member and h is the height of the member.
For example, to calculate the moment of inertia of a rectangular beam with a width of 10 inches and a height of 20 inches, the formula would be:
I = (10 * 20^3)/12 = 6,666.67 in^4
This calculation can be used to determine the member's ability to resist bending under different types of loads and stresses.
