# Cantilever beam
# Scope: Elastic rectangular cantilever under transverse end load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 300 mm
width = 25 mm
depth = 12 mm
load = 20 N
modulus = 69 GPa

inertia := width*depth^3/12 [mm^4]
deflection := load*length^3/(3*modulus*inertia) [mm]

check deflection budget: deflection <= 2 mm

scenario alternative: length = 240 mm
