8–7 For the screw clamp shown, a force is applied at the end of the handle 3.5
in from the screw
centerline. The 3/8
in diameter handle is made of cold-drawn AISI 1006 steel. The screw is
3/4
in-10 UNC and is 8 in long, overall. The maximum possible length of screw in the clamping
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?
