Rear cargo ramp and autoclave: what they have in common

1. Step 1. Rear cargo ramp — is part of — Cargo aircraft. A lowering rear ramp for loading vehicles.
2. Step 2. Cargo aircraft — has part — Landing gear. Landing gear for dirt airstrips.
3. Step 3. Landing gear — has part — Shock absorber. Shock struts.
4. Step 4. Shock absorber — uses — Hydraulics (Pascal’s law). Oil flows through valves, damping oscillations.
5. Step 5. Hydraulics (Pascal’s law) — is used in — Manometer. A liquid manometer is a pair of communicating vessels: the difference in levels shows the pressure.
6. Step 6. Manometer — is part of — Autoclave. The gauge shows whether the steam pressure in the chamber is high enough to sterilize.
