Does the angle of force application matter?

Yes, this assumes force is applied perpendicular to the lever arm; at other angles, multiply by sin(θ).

Torque Calculator

Torque is the rotational equivalent of force, calculated from the applied force and the perpendicular distance from the pivot point.
