Torsion Springs - Design Theory - Spring-I-Pedia

Torsion Spring Design Theory. Torsion springs are stressed in bending. Rectangular wire is more efficient in bending than round wire, but due to the premium cost of rectangular wire, round wire is preferred. Torsion springs, whose ends are rotated in angular deflection, offer resistance to externally applied torque. The wire itself is subjected ...
