# Linear actuator selection
# Scope: Axial force, speed and efficiency power budget.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

force = 500 N
velocity = 10 mm/s
efficiency = 0.5

mechanical := force*velocity [W]
input := mechanical/efficiency [W]

check input power budget: input <= 20 W

scenario alternative: force = 400 N
