Re: Physics Quiz
Hmm... cool problem.
Given that torque is F*r and force in the direction of the axle will cancel out, the magnitude of friction = (tau/r)*sin(pi/2-theta) and direction = theta-pi/2. That was quickly arrived at so I probably missed something.
****angle is given relative to the angle of the axle*********
