# Simply supported beam
# Scope: Simply supported rectangular beam with central point load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 1 m
width = 30 mm
depth = 50 mm
load = 1000 N
modulus = 200 GPa

inertia := width*depth^3/12 [mm^4]
deflection := load*length^3/(48*modulus*inertia) [mm]

check deflection budget: deflection <= 2 mm

scenario alternative: length = 0.8 m
