An m = 2kg cylinder attached to a slender bar as shown in the link below is rotated through an angle of 60^o by a torque T. The mass and mass moment of inertia of the slender bar can be ignored. If the cylinder starts from rest in State 1 and has an angular velocity of ω₂=1 rad/s in State 2, what is the applied torque, T if friction at the bearing can be ignored?
