Understanding torsion springs and some key design calculations
Simply, spring rate is the change in load per unit deflection. It can be calculated using: Where: E = modulus of elasticity (psi) D = mean diameter (inches) d = wire size (inches) N = number of active coils. Consider the example of a torsion spring design with a wire diameter of 0.05 inches, a mean diameter of 0.45 inches and three active coils.
