SUMMARY

To determine how far a 2.0-cm-diameter piston must be pushed down to lift an 8.0-cm-diameter piston by 20 cm in a hydraulic lift, the principle of incompressible fluid mechanics is applied. The volume displaced by the smaller piston must equal the volume displaced by the larger piston. Using the equation for volume (V = πr²h), the calculations reveal that the smaller piston must be pushed down approximately 0.625 cm to achieve the desired lift of the larger piston.

PREREQUISITES
  • Understanding of hydraulic systems and Pascal's principle
  • Familiarity with the formula for the volume of a cylinder (V = πr²h)
  • Knowledge of the concept of incompressible fluids
  • Basic algebra for solving equations
NEXT STEPS
  • Study Pascal's principle in hydraulic systems
  • Learn about the properties of incompressible fluids
  • Explore the applications of hydraulic lifts in engineering
  • Practice solving problems involving volume displacement in hydraulics
USEFUL FOR

Students studying physics, engineers working with hydraulic systems, and anyone interested in fluid mechanics and its applications.
