a wheel with rotational inertia I is mounted on a fixed, frictionless axle. the angular speed omega of the wheel is increased from zero to omega final in a time interval T. whats the average net torque during this time interval??
a stick of mass m=2 kg and length L=1m is pivoted about its end. Mass M = 32 kg is attached to the stick at a distance r=0.250 m from the pivot point. This mass is negligible size. What is the net torque on the system when it is released from the horizontal position? remember to consider the...
