If the worker pushes on it with a horizontal force F , applied perpendicular to the pipe, determine the pipe’s angular velocity when it has rotated through angle θ about the z axis, starting from rest. Assume the pipe does not swing. Units Used: Mg 10 3 kg = Given: M 16 Mg = 90 deg = k G 2.7 m = r 0.75 m = F 50 N = l 3m
