# Linear-guide block loads
# Scope: Two rails sharing vertical load and roll moment; no carriage rating model.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

load = 500 N
moment = 20 N*m
railSpacing = 200 mm

railA := load/2+moment/railSpacing [N]
railB := load/2-moment/railSpacing [N]

check both rails compressed: railB >= 0 N

scenario alternative: load = 400 N
