What does it mean when it says pushed into the back of a back?

block, that was a poorly placed typo.


If the forces are broken down into components, then both would, it seems to me, have the same x and y forces (because the same P force is being applied at the same angle). I just question this because I don't know if the bar (or hands, or anything that can push, really) would be any different than the rope. I've been told that it is, but I can't seems to understand why.



think the bar situation will increase the normal, since it is pushing "down" on the box and the normal has to compensate for this "increase in weight". Wouldn't this decrease the normal force because the y component of the force P is also working in the positive y direction?
