How does Pascal's principle relate to hydraulic lifts? Hydraulic lifts use Pascal's principle to amplify force. Pascal's principle tells us that pressure is transmitted equally throughout a static fluid. A small force exerted on a small area over a large distance is translated into a large force exerted on a large area over a small distance in a device like a car lift.
In this mechanical engineering project, you will apply the principles of hydraulics to build a working model of a knuckle crane that will pick up and move a load. You can use syringes to act as the hydraulic cylinders. The plunger of the syringe acts as the piston in the hydraulic cylinder.
