The 4-in.-radius wheel weighs 6 lb and turns about its y′-axis with an angular velocity p = 40π rad/sec in the direction shown. Simultaneously, the fork rotates about its x-axis shaft with an angular velocity w = 10π rad/sec as indicated. Calculate the angular momentum of the wheel about its center O′. Also compute the kinetic energy of the wheel.
