A thin annular disc has an inner radius of 50mm and an outer radius of 150mm and rotating uniformly at 5000 RPM. Determine the hoop and radial , stresses at the inner and outer radii? Show the variation of these stresses with r and the radius for which , is maximum. Assume that the disc is made of steel for which p= 7480 kg/m and v=0.3.
