Normal Reaction : When a rod rests against a smooth wall, we know that the direction of the reaction is normal to the wall. I understand that the peg is a point, hence there is no meaning to the statement of the reaction force being "normal" to it. However, how is the reaction force normal to the rod? Is it also the case for a rope tied to the peg and through which a tension force exists?
Answers would be most welcome.
