4. Opening angle
Several factors are used to determine the characteristics of a spring and they are similar for both
the coil and torsional spring types. Wire diameter, material type, the number of coils and the
physical shape of a spring all determine how a spring will act. Once these characteristics are built
into a spring, they determine the spring rate and the free length in a coil spring or the opening
angle and spring rate in a torsional spring.
