Torsion springs: These are springs that experience momentum due to a force that is being applied outside of the center of gravity of the spring, specifically in one of the spring legs.Such force would make the spring rotate if we did not fix the other leg. Since the spring does not rotate, it deforms because of the torsional force, and it stores energy like …torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied.

As the torque is called moment, it is commonly represented M. The SI unit for torque is the newton metre (N•m). The units of pound-force-foot, pound-force inch, and ounce-force-foot are also used for toque. For all these units, the word "force" is often left out, such as pound-force-inch, abbreviate to simply "pound-inch". Power transmitted. Power is the ratio between the work done and the time taken and can be expressed as. Note! - a machine must rotate to produce power! A machine with no rotation can deliver torque - like an electric motor - but since no distance is moved by force - no power is produced. As soon as the machine starts to rotate power is produced.2.3 Binormal vector and torsion.
