For the screw clamp shown, a force is applied at the end of the handle 3 in from the screw centerline. The in diameter handle is made of cold-drawn AISI 1006 steel. The screw is in-10 UNC and is 8 in long, overall. The maximum possible length of screw in the clamp- ing region is 6 in. (a) What screw torque will cause the handle to bend permanently? (b) What clamping force will the answer to part (a) cause if the collar friction is neglected and if the thread friction is 0.15? (c) What clamping force will cause the screw to buckle? (d) Are there any other stresses or possible failures to be checked?

The piston in an engine is attached to a connecting rod AB, which in turn is connected to a crank arm BC (see figure). The piston slides without friction in a cylinder and is subjected to a force P (assumed to be constant) while moving to the right in the Figure. The connecting rod. with diameter d and length L, is attached at both ends by pins. The crank arm rotates about the axle at C with the pin at B moving in a circle of radius R. The axle at C, which is supported by bearings, exerts a resisting moment M against the crank arm.
