A torsion spring is a spring that works by torsion or twisting. Mechanical energy is created when it is twisted. When it is twisted, it exerts a force (torque) in the opposite direction, proportional to the amount (angle) it is twisted. A torsion bar is a straight bar of metal that is subjected to twisting (shear stress) about its axis by torque applied at its ends.
