Consider the arrangement shown below. It consists of a bolt, clevis and plate. Since, the clevis and the plate press against the bolt, the bolt will be acted upon by forces 1,2,3 (as shown).
There is something called as bearing stress which will act on the bolt in this case.
I don't exactly get what is this bearing stress. According to what I know about stress, when a body is acted upon by loads, we consider an area in the body and on this area internal resistive forces are developed to oppose external loads, then we calculate the intensity of these internal resistive forces on that area to determine the stress.
The bearing stress in this bolt correspond to what internal resistive forces?
On which area these internal resistive forces are taken?
I've thought a little about it, and came with this, but not quite sure if this is what is exactly meant by bearing stress. Does the bearing stress correspond to the internal resistive forces shown by red? at the midplane?
