# Mechanical duty-cycle loads
# Scope: Two-state power budget; supplied on/off power.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

onPower = 100 W
offPower = 5 W
onTime = 10 s
offTime = 50 s

duty := onTime/(onTime+offTime)
average := duty*onPower+(1-duty)*offPower [W]

check average power budget: average <= 25 W

scenario alternative: onPower = 80 W
