# Bent-part flat-length estimate
# Scope: Two tangent straight segments plus one neutral-axis bend allowance.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

legA = 50 mm
legB = 30 mm
angle = 90 deg
radius = 2 mm
thickness = 1 mm
kFactor = 0.4

bend := angle*(radius+kFactor*thickness) [mm]
flatLength := legA+legB+bend [mm]

check flat length envelope: flatLength <= 90 mm

scenario alternative: legA = 40 mm
