# Shaft deflection and bearing slope
# Scope: Simply supported solid circular shaft with central point load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 100 N
length = 300 mm
diameter = 15 mm
modulus = 200 GPa

inertia := pi*diameter^4/64 [mm^4]
deflection := load*length^3/(48*modulus*inertia) [mm]

check deflection budget: deflection <= 0.2 mm

scenario alternative: load = 80 N
