Hi, I haven't done beam deflection before. My text book shows the usual simple beams with a perpendicular force acting on it. This one is a lot more complicated. I'm pretty sure the forces acting in the horizontal direction have to be added into this some how. Can someone look at the attached file and give me some pointers on what I did right and wrong? point E, D, C, and B are all pin connections. Point B hooks to the bucket, Point C is a hydraulic cylinder that connects to the bucket for tilting. Point D is a hydraulic cylinder that rasies and lowers the arm. Point E is a pin connection to the tractor. The moment of inera has been calculated by the beams cross section the force goes though. Thank you.
