# Scissor-lift force and travel
# Scope: One ideal scissor stage; horizontal actuator across the full base.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

link = 0.5 m
angle = 30 deg
load = 500 N

height := 2*link*sin(angle) [m]
width := 2*link*cos(angle) [m]
drive := load/tan(angle) [N]

check actuator force budget: drive <= 1000 N

scenario alternative: link = 0.4 m
