[SOLVED] I think the Geometry is what is getting me So I am doing 26 right now and I can't seem to get the cobwebs cleared out of my head. I know that the max Moment will be 80 kN*m and that will occur when I move point a such that the cable makes a 90 degree angle with the boom. At that point x will become the hypoteneuse of a right triangle. I also know that theta is still 30 after the move. I should be able to find x by using trig, but for some reason I cannot figure out how to incorporate the 1.5m. Any ideas?
