Consider a continuous body occupying the region D in space. If the body is rotating about a line L, the moment of inertia of the body is given by IL = (1) D where o is the density (mass per unit volume) of the object and r(x, y, 2) is the distance of a point (x, y, z) inside the body to the line L. Explain how to derive Formula (1) in your own words. Your answer should not more that two pages
