Homework Statement
Suppose I have a brick that's sitting at the edge of a disc that is rotating clockwise with uniform circular motion.
I what direction(s) are the forces of static friction acting?
Homework Equations
a = v^2/r
The Attempt at a Solution
I know that a centripetal force from static friction acts on the brick to keep it moving in a circle along with the disc. Is there also a static friction force acting on the brick tangentially in a counterclockwise direction to prevent the disc from slipping under the brick?
