# Steering geometry and turning radius
# Scope: Bicycle steering model at low speed; no tire slip.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

wheelbase = 1 m
steer = 30 deg

radius := wheelbase/tan(steer) [m]

check turn radius budget: radius <= 2 m

scenario alternative: wheelbase = 0.8 m
