# Problem: A torque can be exerted on a body with a fixed axis of rotationa. only by a centripetal force.b. only by a force directed radially outwards.c. only by a tangential force.d. only by a force with a component directed radially outwards.e. by any force not pointing directly toward or away from the axis of rotation.

Torque:

$\overline{){\mathbf{\tau }}{\mathbf{=}}{\mathbf{r}}{\mathbf{F}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{\mathbf{\theta }}}$ r is the distance from the fixed axis of rotation, F is the force, and θ is the angle between r and F.
