Reference no: EM1344649

Q. A rotating flywheel has been proposed as a means of temporarily storing mechanical energy in an automobile, providing an energy source for the car. The energy that can be stored in this way is limited by the size and weight of the flywheel and by the maximum angular velocity it can attain without flying apart. Assume a solid cylindrical flywheel of radius 70 cm and mass 70 kg rotates at a maximum angular velocity of 230 rad/s. Find out the maximum rotational energy of the flywheel.
