In a hydraulic lift a small force on a small piston lifts a car on a large piston. The force gain is the:
ABuoyant force gain
BGauge pressure gain
CSurface tension gain
DMechanical advantage
Answer & Solution
Correct answer: D. Mechanical advantage
1. The same pressure acts on both pistons.
2. A bigger area gives a bigger force.
3. The factor of increase is the mechanical advantage.
