# Question

The figure shows a crank loaded by a force F = 190 lbf which causes twisting and bending of the ¾ -in-diameter shaft fixed to a support at the origin of the reference system. In actuality, the support may be an inertia which we wish to rotate, but for the purposes of a strength analysis we can consider this to be a static’s problem. The material of the shaft AB is hot-rolled AISI 1018 steel (Table A–20). Using the maximum-shear-stress theory, find the factor of safety based on the stress at point A.

Given the summing amplifier shown, select the values of R2 that will produce an output voltage of –3v. This problem illustrates that the strength of a machine part can sometimes be measured in units other than those of force or moment. For example, the maximum speed that a flywheel can reach without yielding or fracturing is ...Repeat Prob. 5–25 using maximum-shear-stressA tube has another tube shrunk over it.
