# Weld-group preliminary sizing
# Scope: Uniform fillet weld throat shear; no eccentric load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

force = 2000 N
leg = 3 mm
length = 100 mm

throat := leg/sqrt(2) [mm]
stress := force/(throat*length) [MPa]

check weld stress budget: stress <= 80 MPa

scenario alternative: force = 1600 N
