... Since the friction force is tangential to a point on the rim of the wheel, it is perpendicular to the radius line connecting this point with the center of the wheel. The torque of this force about the axis through the center of the wheel is then = rf sin 90.0º = rf, and the friction force is ...

... Torque is a vector quantity. The direction of the torque vector is at right angles to the plane containing both r and F and lies along the axis of rotation. (In the example shown in the diagram torque, T, points out of the page). A force acting on the rim of an object will cause the object to rotate ...
