Hey. This is my first post, I'm a Senior in Mechanical Engineering, I will help others as far as I can. I'm trying to solve the problem from the picture. The shaft is loaded with 2 transverse loads, 2 moments and 2 torques. The critical point is immediately to the left of "B". The material is AISI 1020 HR steel. The shaft has a diameter of 1.00 inch. I'm trying to figure out if the shaft will fail. As of now I've figured out that I have to obtain the general stress state at point B. My question is, how does the stress at point "C" affect the stress at point "B"?? If there was only 1 moment and 1 torque affecting point "B", that would be an easy problem, but having the other stress is confusing me. Any ideas? THAKS!!
