Torque is the rotational equivalent of force. It measures the tendency of a force to cause rotation about an axis, calculated as tau = F * d * sin(theta).

When is torque maximized?

Torque is maximized when the force is applied perpendicular to the lever arm (theta = 90 degrees), because sin(90) = 1.

What are the units of torque?

Torque is measured in newton-meters (N*m). Note that while N*m has the same dimensions as joules, torque and energy are different physical quantities.
