1. The problem statement, all variables and given/known data Ok not really a school problem but i was just thinking of how to solve it. How would i find the moment of inertia of a pyramid with base side length l and height h? If the axis of rotation is along the z axis? 2. Relevant equations I = Summation of mrsquared 3. The attempt at a solution Ok so my approach is to find the geometrical center of the pyramid first. I would know its easy to cut each of the diagonal lengths by 2 and drawing a straight perpendicular line down, but i wanted to try some integration because i just learned it a week ago. I had problems setting up the integral, so could anyone give me a hint or 2?
