Homework Help: Physics

Posted by Karla on Tuesday, March 27, 2007 at 1:52pm.

Forces F1=7.50N and F2=5.30N are applied tangentially to a wheel with radius 0.330 m. What is the net torque on the wheel due to these two forces for an axis perpendicular to the wheel and passing through its center?

It depends upon whether or not the forces F1 and F2 are both in the same rotational direction. It they are, add the torques. If not, subtract one from the other. For a tangential force, torque = (force)x(radius)
