Hi all, I just started learning engineering mechanics this semester,so what i'm about ask may be a basic question in the subject.I came across a bracket that is used in a industrial equipment (i have attached a sketch as image).The bracket is used to mount a hydraulic cylinder.The cylinder has a clevis which is connected to the eye of the bracket with a pin joint.The bracket is located with two dowels and has 4 bolts connecting it with the the base frame. My question how to size the dowel?. My approach is that the two dowels are the ones taking the shear load and the four bolts,with the under head friction prevent the rotation of the bracket. But the problem if there were no bolts , can the bracket rotate about the dowels ?.Or would it resist the rotation ? Also what will be the load on the dowel and the bolts ?I'm not sure how to do it. Thanks for going through the post .And sorry if i have misstated something.
