Homework Help: engineering

Posted by HELP PLEASE! DOn't know How to do it!!! :( on Tuesday, October 11, 2011 at 12:40am.

A slotted bar is attached to the origin and rotates in the horizontal plane with a constant angular velocity of 0.665 radians/s . The bar moves a roller weighing 33.6 lb along the cam's perimeter. A spring holds the roller in place; the spring's spring constant is 1.34 . The friction in the system is negligible. When theta = 101 degrees, what are Fr and F(theta), the magnitudes of the cylindrical components of the total force acting on the roller?
