# Spring energy and required stroke
# Scope: Linear spring stored energy at supplied compression.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

rate = 5 N/mm
compression = 20 mm

force := rate*compression [N]
energy := rate*compression^2/2 [J]

check stored energy budget: energy <= 2 J

scenario alternative: rate = 4 N/mm
