# Planar truss forces
# Scope: Symmetric two-bar pin-jointed truss; only axial forces.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 1000 N
angle = 45 deg
area = 100 mm^2

axial := load/(2*sin(angle)) [N]
stress := axial/area [MPa]

check axial stress budget: stress <= 100 MPa

scenario alternative: load = 800 N
