# Nominal contact pressure
# Scope: Average pressure on a rectangular contact patch.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 1000 N
width = 20 mm
length = 30 mm

pressure := load/(width*length) [MPa]

check pressure budget: pressure <= 3 MPa

scenario alternative: load = 800 N
