Question
![11.7 (A/B). A solid shaft carrying a flywheel of mass 100 kg and radius of gyration 0.4m rotates at a uniform
speed of 75 rev/min. During service, a bearing 3 m from the flywheel suddenly seizes producing a fixation of the shaft
at this point. Neglecting the inertia of the shaft itself determine the necessary shaft diameter if the instantaneous
shear stress produced in the shaft does not exceed 180 MN/m². For the shaft material G= 80 GN/m². Assume all
kinetic energy of the shaft is taken up as strain energy without any losses.
