1.	SI unit of moment arm , power , physical quantity plzz tell
Answer» In this concept the moment arm, the distance from the AXIS of rotation, plays an important role. The LEVER, pulley, GEAR, and most other simple machines create MECHANICAL advantage by changing the moment arm. The SI unit for moment is the newton meter (kgm²/s²).
