Determine the kinetic energy of the plate of Prob. 18.2.

Prob. 18.2

A thin rectangular plate of weight 15 lb rotates about its vertical diagonal AB with an angular velocity ω. Knowing that the z axis is perpendicular to the plate and that ω is constant and equal to 5 rad/s, determine the angular momentum of the plate about its mass center G.
