A circular membrane of radius a, thickness t, and weight per unit area w is simply supported along its edge and
subjected to an in-plane radial load of T lb/unit length of circumference. Determine the radial stress σr in the
membrane and the first three natural frequencies fi of lateral vibration of the membrane. Figure 55.1 Material Properties
