Orque can be calculated by multiplying the force (n) applied at 90β to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is nβ
m. if the force (at 90β 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?
