Question

A 1.875-in.-diameter solid steel shaft supports loads PA = 230 lb, PC = 560 lb, and PE-230 lb, as shown. Assume that LAB = 8 in., LBC = 23 in., LCD = 10 in., and LD-14 in. The bearing at B can be idealized as a roller support, and the beargt D can be idealized as a pin support. Determine the magnitude of the maximum bending stress in the shaft. A B LA LBC CD LDE Answer: σmax- ksi

Answer 1

Given Dia of shift = 1.075 in maximum torque while seeing the value is 560 lb at point c Maximum Torque = F_s times x d^3/16 560 = F_s times pi times 1.075^3/16 F_s = 432.66 lb/in
