Torque can be calculated by multiplying the force (N) applied at 90 degrees to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N*m. If the force (at 90 degrees to the lever arm) applied is 15N and it is applied at 2.0m from the pivot point (point of rotation), what is the torque on the lever? please include units in the answer!!!
