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?

An upward applied force of 10 lbf is applied to a body that has been dropped. Assume the usual value for acceleration due to gravity. If the object weighs 40 lbm, what is the vertical acceleration of the object in ft/s2 ? Draw a free body diagram and label your axes. ANSWER should be between ( 20-25 ft/s2)

Three forces are applied to an object, as shown in the figure.

Chapter 01, Problem 66 Three forces are applied to an object, as shown in the figure. Force F1 has a magnitude of 21.8 newtons (21.8 N) and is directed 30.0° to the left of the ty axis. Force F2 has a magnitude of 14.3 N and points along the +x axis. What must be the (a) magnitude and (b) direction (specified by the angle 6 in the drawing) of the third force F3 such that the vector sum of the three...
