2) [30 pts] C-clamp with handle, power screw For the C clamp shown, a force is applied at the end of the 0.375 in diameter handle. The screw is a 0.75 in-6 Acme thread (from Figure 8-3), and is 10.4 in long overall, with a maximum of 8 in possible in the clamping region. The handle and screw are both made from cold-drawn AISI 1006 steel. The coefficients of friction for the screw and the collar are 0.15. The collar,...

A single-square threaded 35-mm power screw is 35 mm in diameter with a pitch of 5 mm. A vertical load on the screw reaches a maximum of 5 kN. The coefficients of friction are 0.06 for the collar and 0.09 for the threads. The frictional diameter of the collar is 45 mm. Find the overall efficiency and the torque to "raise" and "lower" the load Repeat this problem if ACME screw is used in this design.
