Chapter 14, Problem 49(choose chapter or problem)
4950 The tendency of a lamina to resist a change in rotationalmotion about an axis is measured by its moment of inertia aboutthat axis. If a lamina occupies a region R of the xy-plane, andif its density function (x, y) is continuous on R, then the momentsof inertia about the x-axis, the y-axis, and the z-axis aredenoted by Ix , Iy , and Iz, respectively, and are defined byIx =Ry2 (x, y) dA, Iy =Rx2 (x, y) dA,Iz =R(x2 + y2) (x, y) dAUse these definitions in Exercises 49 and 50. Consider the rectangular lamina that occupies the regiondescribed by the inequalities 0 x a and 0 y b. Assumingthat the lamina has constant density , show thatIx = ab33 , Iy = a3b3 , Iz =
