are quite common. Car brakes depend on a small force applied at the brake exerting a

large force on the wheel to stop the car.

I selected two different sized glass syringes and connected them with a rubber tube

filled with water. This is shown in the diagram.

How it Worked

I out weights on the large syringe and found out the smallest weight that would raise

this by putting this smaller weight on the smaller syringe. I have calculated the

mechanical advantage for each system. The ...
