Unformatted text preview: factor of safety for the shear stress in the key using the Goodman failure criteria is 2.0. c. Calculate the infinite-life fatigue factor of safety for the normal stress on the side of the key (crush) using the Goodman failure criteria for the value of h calculated above. d. Calculate the yield factor of safety for both shear and crush for the value of h calculated above. 12 P = 400 + 800sin(10t) (t = time in seconds) Fixed shaft (2.0 dia) does not rotate Arm Key fixes arm to shaft h h 3.0...
