Hello all new to the forums but I have a question. I need to find out the force that holds two pressed objects together. For example I have a piece with a diameter of 1.000 in and another piece (the shaft) with has a diameter of 1.001. The shaft is inserted .25in into the 1.000in opening. The open diameter is heated up while the shaft is frozen and then the shaft is inserted into the opening. I need to pretty much figure out how to find how much force the shaft can take before it starts to spin in the other pieces open diameter. Im assuming there is friction force and the force of the two objects pressed together I just can't seem to figure out how to go about finding these forces.
