WebChoose a coordinate system with the pivot point or axis of rotation as the origin of the selected coordinate system. Determine the angle between the lever arm r → r → and the force vector. Take the cross product of r → and F → r → and F → to determine if the torque is positive or negative about the pivot point or axis.
