How to calculate the torque of spring?
The torque means axial torsion and reactive force an object is imposed. It's often measured by torque wrench. The units are in Newtons. The common object impose torsion is worm-and-nut，transmission shaft, and so on.The torsion is important to constant force spring. Below is the computational formula of torsion for torsion spring:

spiral spring torsion

E is the modulus of rigidity of wire: music wire E=21000; stainless spring wire E=19400; phosphor bronze wire E11200; brass wire E=11200.
Dn indicate the inner diameter of spring at free state
B indicate the width of section
H indicate the thickness of section
