# Bolt shear and bearing
# Scope: Equal direct shear sharing; threads not in shear plane.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 2000 N
count = 4
diameter = 6 mm

area := pi*diameter^2/4 [mm^2]
stress := load/(count*area) [MPa]

check shear stress budget: stress <= 100 MPa

scenario alternative: load = 1600 N
