Suppose the collar of Prob. 5–31 is tightened by using a screw torque of 190 lbf .in. The collar material is AISI 1040 steel heat-treated to a minimum tensile yield strength of 63 kpsi.
(a) Estimate the tension in the screw.
(b) By relating the tangential stress to the hoop tension, find the internal pressure of the shaft on the ring.
(c) Find the tangential and radial stresses in the ring at the inner surface.
(d) Determine the maximum shear stress and the von Misses stress.
(e)What are the factors of safety based on the maximum-shear-stress hypothesis and the distortion energy theory?
