A 0.125-m diameter and 1.5-m long circular shaft has a flywheel at one end and rotates at 240 rpm. The shaft is suddenly stopped at the free end. Determine the maximum shear stress and the maximum angle of twist produced by the impact. The shaft is made of steel with G = 80.5 GPa, v = 0.3; the weight of the flywheel is W = 1.09 kN; and the flywheel has a radius of gyration of r = 0.35m. Note: Kinetic energy Ek = Ww²r²/2g = TO/2. Here w, g, T, and represent the angular velocity, acceleration due to gravity, torque, and angle of twist respectivelv.
