Which of the following statements are true? The magnitude of torque is the same for any axis of rotation you choose. The vector r points from the axis of rotation to the point where the force is applied. The lever arm is the distance between the point where a force is applied and the axis of rotation. Torque has units of N m. If vectors r and F are parallel, the torque is largest. If you point your fingers along the vector r and curl them in the direction of F, your thumb points in the direction of the torque.
