Homework Statement



Torque is a minimum when the direction of a force is parallel to the radius vector.
True or False

Homework Equations



None

The Attempt at a Solution


I say true because my book gave an example of a seesaw, where if you push down perpendicular to the radius, the torque will be the largest. Would you guys agree?

Yes that is true, when the force is parallel to the radius vector, the torque is zero by way of the definition of torque T=r x F where x means the cross product.
