# Flexure hinge and compliant motion
# Scope: Small-deflection rectangular cantilever flexure; end transverse force.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 40 mm
width = 10 mm
thickness = 0.5 mm
force = 1 N
modulus = 200 GPa

inertia := width*thickness^3/12 [mm^4]
deflection := force*length^3/(3*modulus*inertia) [mm]
stress := 6*force*length/(width*thickness^2) [MPa]

check elastic stress budget: stress <= 250 MPa

scenario alternative: length = 32 mm
