I'm asked to determine the deflection of the tip of a beam for a 2000N load. The section is rotated 15 degrees. The load application point is through the centroid of section. Another way to describe the picture is that the beam is cocked to one side by 15 degrees and the load almost at one corner [maybe width*cos(15)] aiming
So, how would I set this problem up? We're asked to determine the deflection of a beam location for a 2000N load. However, the force is directed up the corner NOT centroid. In other words, at beam corner up through the side wall. Kind of like a ledge holding a flower pot. Given load=2000N, on the tip of a 1m beam. Beam
