Basically the collar has two forces acting on it. The rotational force and the gravitational force. I used the y-axis for the force components parallel/opposite to the normal force and multiplied the normal force by the kinetic friction which should have given me the frictional force. But the...

Homework Statement A small 350-g collar C can slide on a semicircular rod which is made to rotate about the vertical AB at a constant rate of 7.5 rad/s. The coefficients of friction are μs = 0.25 and μk = 0.20. Homework Equations Tangent Velocity= Radians*radius Normal acceleration an=...
