Sorry. I was thinking actual load and typing something different. Th shaft must withstand a linear load of 30,000 Lbs without yeild that is no problem. Forces will not always be linear is the problem, it will have forces (approximately 15,000 Lbs actual) applied to it at about a 45 degree...
Would 4140 Cold Drawn be a good material used in a 1 inch shaft that needs to withstand 30,000 Lbs tensile strength and also stand up well in a 45 degree bending moment? If not any sugestions? I know the tensile is no problem.
