A square-threaded power screw with single thread is used to raise a load of 25,000 lb. The screw has a mean diameter of 1-in. and four threads per inch. The collar mean diameter is 1.5 in. The coefficient of friction is estimated as 0.1 for both the thread and the collar. Assume the length of thread engagement is 1.5 times the outside diameter of the screw. 1. Calculate the safety factor for the power screw to fail in torsion. Assume...

A steel cable with a yield strength of 35 ksi is used to support a load of 10000 lb. Select the diameter of the cable using a factor of safety of 2.5. A standard steel specimen having a diameter of 0.502 in, and a gauge length of 2.00 in is used in a tension test. At 6000 lb the deformation is recorded as 0.00212 in. The load at the yield point is 7130 lb and the ultimate load is 11520...
