# Vehicle speed and gearing
# Scope: Rolling speed from motor speed, ideal reduction and wheel radius.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

motorSpeed = 3000 rpm
ratio = 10
radius = 0.15 m

speed := motorSpeed*radius/ratio [m/s]

check speed budget: speed <= 6 m/s

scenario alternative: motorSpeed = 2400 rpm
