What is the formula for the moment of inertia of a rectangular section?

Step 1: Understand that the moment of inertia is a measure of how difficult it is to change the rotation of an object.
Step 2: Identify the shape you are working with, which in this case is a rectangle.
Step 3: Recognize the dimensions of the rectangle: 'b' is the width and 'h' is the height.
Step 4: Use the formula for the moment of inertia of a rectangular section, which is I = (b * h^3) / 12.
Step 5: Plug in the values of 'b' and 'h' into the formula to calculate the moment of inertia.
