Determine the kinetic energy of the rod of Prob. 18.15.
Prob. 18.15. A rod of uniform cross section is used to form the shaft shown. Denoting by m the total mass of the shaft and knowing that the shaft rotates with a constant angular velocity ω, determine
(a) the angular momentum HG of the shaft about its mass center G,
(b) the angle formed by HG and the axis AB.
