#### zasdfgbnm

1. Homework Statement
A rigid rod is put in a global bowl horizontally.The bowl is shaggy.Do friction forces exist where the rod and the bowl touch?
2. Homework Equations

3. The Attempt at a Solution
If the bowl is smooth,it's clear that friction forces don't exist.But what if the bowl is not smooth?

Friction is a resistance to force. If the rod is otherwise stabilized by balanced forces x,y , then the effect of friction is not a static consideration.
