Code Number: 2B20.60
Demo Title: Work Done by a Piston - Jack
Condition: Excellent
Principle: Force and Pressure
Area of Study: Fluids
Equipment:
Hydraulic jack, Stand for jack, boards (1 & 2 inches), Plexiglas demo jack.
Procedure:
Some new boards will have to be cut when needed. 2 X 4's seem to work the best. Clamp the jack stand very securely to the table.
The demo jack is used only to show the height differential between the two pistons. Any real pressure applied to the system will break the Plexiglas seals. Lubricate the small piston o-rings with Vaseline before each use.
