In the video we can see a pneumatic system. First the video shows the system drawn realistically, then its diagram.
- a) What is Pascal’s Principle?
- b) Why piston 1 moves faster than piston 2?
- c) What is the function of the valves?
- d) How is the direction of movement in the piston controlled?
