Torque can be calculated by multiplying the force (N) applied at 90āˆ˜ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is Nā‹…m. If the force (at 90āˆ˜ to the lever arm) applied is 15 N and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
