Begin a revision of the first study of this part by reconsidering the restraints
utilized. In many problems the restraints are unclear or questionable and you
need to consider other restraint cases. You previously restrained all the three
translations on the two small cylindrical surfaces. That makes those surfaces
perfectly rigid. That would be almost impossible to build. It is likely that the
holes were intended to be bolt holes. Then the applied backward (-z) pressure
load would probably require the development of tension reaction forces along
the back (-z) half of the bolt cylinder. That would not happen because an air gap
would open up. Also, a bolt usually applies a restraint to the surface under the
bolt head (in addition to a bolt bearing load on its cylindrical part), and that is
not in the original choice of restraints. Furthermore, the bracket seems to be
attached to some rigid object under it and therefore you would expect the back
edge of the bracket to be somehow supported by that object when that region of
