A special C-clamp uses a 0.75-in.-diameter Acme thread and a collar of 1-in. effective mean diameter. The collar is attached rigidly to the top end of the externally threaded member. Determine the force required at the end of the 6-in. handle to develop at 300-lb clamping force. The friction coefficient in the thread is 0.2 and in the collar is 0.15. what is efficiency of the power screw
