Question

Expert,Static friction depends on nature of surface but limiting friction doesn't depend on are/shape. Isn't that contradicting? hellppp

Answer 1

Friction doesn't depend on the shape anywhere. It depends on the surface and their interactions. So, the interaction is microscopic and that's why we consider the normal force as a factor which controls the static friction. There are no contradiction.
Limiting friction is maximum static friction beyond which a body starts moving.
