2. The C clamp shown in the figure below uses an Acme thread screw. The screw has a diameter of 17 mm and a pitch of 5 mm. The frictional coefficients are 0.15 for the threads and 0.20 for the collar. The collar, which in this case is the anvil striker's swivel joint, has a friction diameter of 25 mm. Find the clamping force if 105 N force applied to the handle at a distance of 100 mm from the...

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,...

PROBLEM 5: Figure shows a screw jack lifting a non- rotating load of 200 kg. The screw jack consists of a single square screw thread with a major diameter of 30 mm and 10 threads per 5 cm. A rotating nut, driven by a leverage arm moves a plain thrust collar with diameter de 50 mm, which in turn lifts and lowers the load. The friction coefficient between the nut and the collar μ -0.25 and the friction coefficient between...

A compressive force of 450 N is to be applied to the two boards in the grip of the C clamp shown in Figure 13. The threaded screw has a mean diameter of 12 mm and advances 2.8 mm per turn. The coefficient of static friction is 0.20. Neglecting any friction at point A Determine the force F which must be applied to the handle at C in order to i. Tighten the clamp to provide the clamping force. ii....
