2B20.60 • Static Pressure: Hydraulic Press
Location: Cabinet 2
Photo Shows the Apparatus Used at the University of Texas at Austin
Instructions/Notes:
- Place two long pieces of wood on the outer edges of the hydraulic press platform placed horizontally as shown in the picture.
- Balance the block of wood that will be split in between these wood pieces.
- You can either place the block so it will be split against the grain or with the grain. If splitting with the grain, be sure to do this further away from the students, as the wood will split and shoot off in different directions.
- Pump the piston to push it up and split the piece of wood.
Demo Staff:
- To lower the piston after use, remove the metal bar from the pumping mechanism and place it over the release valve as indicated in the picture.
- Rotate the valve by one turn counterclockwise to release the pressure. Push down hard onto the piston platform to return it to its original position.
- Be sure to re-tighten the pressure valve by turning it clockwise. If the release valve is too loose, it may leak oil!
- Return the metal bar to the pumping mechanism.
- When putting away, place another piece of wood in the apparatus.
- Dimensions for wooden blocks if more are needed (cm):
- Platform blocks: 23.5 x 3 x 1.75
- Splitting blocks: 8.75 x 8.75 x 2
Safety:
- Be sure to provide safety glasses or goggles for this demonstration. When the block is split, it will shoot the wood in different directions!
- Place this demo further away from students and towards the back of the room to reduce possible projectile collisions on bystanders.
