Hydraulic Brake
For demonstration of the principle of hydraulic breaking system that operates on fluid pressure. It consists of a wheel with a handle for rotating it and hydraulically actuated breaking mechanism which is connected to cylindrical metal reservoir through a flexible pressure tubing. The plunger of the reservoir has a lever handle pivoted at its top for pushing it downward to apply pressure on the fluid inside, which is then forced through the connected tubing to actuate the braking mechanism. Complete apparatus mounted on a wooden base.
