What is the formula for the moment of inertia (I) of a rectangular beam section?

Step 1: Identify the shape of the beam section. In this case, it is a rectangle.
Step 2: Determine the dimensions of the rectangle. You need to know the base (b) and the height (h) of the rectangle.
Step 3: Understand the formula for the moment of inertia. The formula is I = (b * h^3) / 12.
Step 4: Plug in the values of the base (b) and height (h) into the formula.
Step 5: Calculate h^3 (height raised to the power of 3).
Step 6: Multiply the base (b) by h^3.
Step 7: Divide the result by 12 to find the moment of inertia (I).
