DIY Hydraulic Mechanical Arm Model

See pressure transfer through liquid by building and operating a wooden hydraulic arm model.

✅ Make the movement principle visible - Operating a piston transfers pressure to the model arm's hydraulic mechanism.

✅ Connect assembly with the explanation - The DIY format lets you put the mechanism together as a practical project.

Build the links before moving the arm

Follow the supplied assembly guidance and identify the piston connections as the model comes together. This gives the later demonstration a structure you have examined rather than only a finished mechanism to watch.

Use the completed arm for the intended science activity, comparing the movement with the hand pressure supplied to the piston. The approximately 53 x 12 x 30 cm model is not an industrial lifting arm, and adult supervision is recommended.
