Rotational kinetic energy is yet another mass-dependent engineering quantity. An object having a mass moment of inertia I and rotating with angular speed of ω (rad/s) has a rotational kinetic energy which is equal to Determine the rotational kinetic energy of a steel shaft that is 5 ft long and has diameter of 2 in. and is rotating at an angular speed of 100 rpm. Express your answer in SI, BG, and U.S. Customary units.
