# Linkage mechanical advantage
# Scope: Virtual-work ratio from supplied small input/output displacements.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

inputTravel = 20 mm
outputTravel = 5 mm
effort = 10 N
efficiency = 0.8

advantage := inputTravel/outputTravel
outputForce := effort*advantage*efficiency [N]

check force target: outputForce >= 25 N

scenario alternative: inputTravel = 16 mm
