DIY Hydraulic Jack Model

Product Code : SCL-M-12432

DIY Hydraulic Jack Model by Educational Instrument is a hands-on STEM working model designed to demonstrate the principle of hydraulics, fluid pressure, force transmission, load lifting, and Pascal’s Law. It is suitable for school science laboratories, STEM classrooms, physics practical rooms, engineering basics workshops, science exhibitions, and project-based learning activities.

This model helps students understand how pressure applied at one point in an enclosed fluid is transmitted equally in all directions. By using syringes, tubes, water or suitable fluid, and a lifting platform, learners can observe how a small input force can lift a comparatively heavier load. The model is useful for explaining real-life hydraulic machines such as car jacks, hydraulic lifts, excavators, braking systems, and industrial lifting devices.

Product Description

The Educational Instrument DIY Hydraulic Jack Model is developed to make fluid mechanics and pressure concepts easy to understand through practical construction and demonstration. Instead of only studying Pascal’s Law theoretically, students can build and operate a working model that visibly shows force multiplication and hydraulic lifting.

The model generally includes a base structure, lifting arm or platform, syringes or hydraulic cylinders, connecting tube, fluid medium, and support components depending on the model variant. When pressure is applied to one syringe, the fluid transmits pressure through the tube and moves the second syringe, raising the lifting platform.

This DIY model supports inquiry-based STEM learning, allowing students to assemble the parts, test the mechanism, observe movement, and understand the relationship between pressure, area, and force. It is suitable for classroom demonstrations, school projects, science fairs, and introductory mechanical engineering activities.

How to Use DIY Hydraulic Jack Model

Place the DIY Hydraulic Jack Model on a flat and stable surface.

Check that the base, lifting arm, syringes, and connecting tube are fitted properly.

Fill the syringe and tube system with water or suitable demonstration fluid as per the model design.

Remove trapped air bubbles from the tube for smoother operation.

Place a light demonstration load on the lifting platform.

Press the input syringe slowly and observe the movement of the output syringe.

Watch the lifting platform rise due to hydraulic pressure transmission.

Release or pull back the syringe gently to lower the platform.

Repeat the experiment with different loads, input force, and fluid levels.

Record observations in the lab notebook or STEM worksheet.

Empty, clean, and store the model properly after the activity.
