A 5 in diameter 4 splines shaft ( d= 0.85D, w= 0.24D, h= 0.075D ) and permanent fit has a compressive force of 3000 lb. Find the compressive stress if hub length is 2 1/2 in. Ans. 800 psi

Please present drawings/FBD’s illustrating your solution.

(8) An axle (non-rotating) is to be machined from AISI 1144, OQT 1,000°F, to the proportions keyway в shown, with a fillet radius r = 0.2D; F varies 1.SD from 400 lb. to 1,200 lb.; the supports are to the left of B, not shown. Let N = 2 (Soderberg Line). 6" (a) At the fillet, compute D and the 30 maximum tensile stress. (b) Compute D at section B. (c) Specify suitable dimensions. Keeping the given proportions, would a smaller diameter be permissible if the fillet were shot-peened?
