(14) The figure shows a crank loaded by a force F = 190 lbf which causes twisting and bending of the 0.75-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 statics problem. The material of the shaft AB is hot-rolled AISI 1018 steel (S, = 32 kpsi). Using the maximum-shear-stress theory, find the factor of safety based on the stress at point A. Is this theory predicts yielding? (Ans./ n= 0.967, yes)

For two existing torques, what third force at a given distance from the pivot will balance them? Imagine a meter stick set up as in the figure. It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point. For each trial, use the principle of equilibrium (where the sum of torques is zero) to calculate the third, unknown force acting at x3
The variation diagram of the cutting force of the cutting work done with the press shown in the figure is given in the figure. Engine speed is 1400 rpm, flywheel speed is 75 rpm. The moment of inertia of the rotating masses in the engine is 0.75 kgm^2. Calculate the flywheel moment of inertia required for the press so that the velocity unevenness is 0.02. It is known that the engine power is 2 kW.
