Question
Problem 1. The bent steel round bar is fixed in the wall at A. The Young's modulus of the steel bar is 30,000,000 psi and its yield strength is 50,000 psi. If a force F is applied at B. Take F=120 Ibf and 0= 45°. (1) Calculate the stresses at point D and E; (b) Estimate the factor of safety for point D and E using max
