# Torsion-spring rate
# Scope: Supplied angular spring rate; linear range only.
# Status: illustrative worked example; engineering review pending.

rate = 0.02 N*m/rad
angle = 30 deg
preload = 0.01 N*m

torque := preload+rate*angle [N*m]

check torque budget: torque <= 0.04 N*m

scenario alternative: rate = 0.016 N*m/rad
