感谢你，孤独

当你又瘦又好看，钱包里都是自己努力赚来的钱的时候，你就会恍然大悟：哪有时间患得患失，哪有时间猜东猜西，哪有时间揣摩别人？你若盛开，蝴蝶自来，你若精彩，天自安排！

We’re given the situation above and asked to figure out the safety factor for the rod. The material is 6061-T6 aluminum (Sy = 40,000 psi), the length of the rod l = 5 in, the length of the arm a = 6 in, the rod diameter d = 1.25 in, and the force F = 1000 lb. We’re asked to find the safety factor of this assembly using the distortion energy theory. (Problem and image adapted from Machine Design: An Integrated Approach, 4th Ed., by Robert L. Norton.)
