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.
