A spring’s Stiffness affects its
diameter in the viewport.
The Stiffness value of the spring is indicated in the viewport. The stiffer the spring,
the greater its diameter. The Stiffness also affects the spring’s rate of oscillation, with
a stiff spring tending to oscillate faster than a weak spring because of the greater
force that it exerts on the objects it is attached to. The time taken for an oscillation
in such a spring-mass system will also depend on the mass of the attached objects.
Damp
Like Stiffness, there are two input boxes. The left-hand input box denes the damping
for the Below option; the right-hand input box denes damping for the Above option.
All real springs will experience damping while oscillating due to resistance within their
material. Without damping, a spring would oscillate endlessly. For realistic damping,
set a value from 0.1 to 0.5.
