# Lever mechanical advantage
# Scope: Ideal two-arm lever perpendicular to force.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 100 N
loadArm = 50 mm
effortArm = 200 mm

effort := load*loadArm/effortArm [N]
advantage := effortArm/loadArm

check effort budget: effort <= 40 N

scenario alternative: load = 80 N
