1. Step 1. Four-wheel drive — is used in — SUV. Four-wheel drive.
2. Step 2. SUV — has part — Suspension. Long-travel suspension.
3. Step 3. Suspension — has part — Shock absorber. Shock absorbers are part of the suspension.
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 — Hydraulic press. Pascal’s law multiplies the force.
