Parallelogram Law Apparatus Gravesand Manufacturer,Supplier and Exporter in India

Product Code : SCL-MF-12373

The Parallelogram Law Apparatus is a physics laboratory apparatus used for verifying the law of parallelogram of forces and determining the resultant of two concurrent forces. It is designed for school physics labs, college practical rooms, STEM classrooms, and teacher-led mechanics experiments using strings, pulleys, and weights.

Product Description

The Parallelogram Law Apparatus | Gravesand by School Equipments helps students study vector addition through a visible force-board arrangement. In a typical experiment, two known forces act at a point through strings and pulleys, while a third force balances the system to establish equilibrium.

This apparatus is suitable for practical mechanics lessons on concurrent forces, resultant force, equilibrant force, vector diagrams, scale drawing, and graphical verification of force laws. The final supplied configuration may include a force board, pulleys, strings, weight hangers, slotted weights, pins, and drawing sheet arrangement; exact material, board size, and weight set should be confirmed before publishing.

Key Features

• Designed for verifying the parallelogram law of forces in school physics laboratories.
• Supports practical study of resultant force and equilibrant force.
• Useful for teaching vector addition through direct graphical construction.
• Helps students connect force magnitude, direction, and angle in one experiment.
• Suitable for school, college, STEM, and teacher-training laboratories.
• Can be used with pulleys, strings, weight hangers, slotted weights, and drawing sheets, subject to final supply.
• Board size, pulley type, weight capacity, and included accessories should be verified from the supplied apparatus.

Technical Specifications

What's Included in the Kit

How to Use the Parallelogram Law Apparatus | Gravesand

1. Place the apparatus vertically or on the supplied support as per the experiment guide.
2. Fix the drawing sheet to the force board if graphical plotting is required.
3. Pass strings over the pulleys and attach weight hangers to apply known forces.
4. Adjust the weights until the central ring or knot remains in equilibrium.
5. Mark the directions of the three forces on the sheet.
6. Draw vectors to scale and complete the parallelogram construction.
7. Compare the diagonal resultant with the balancing force to verify the law.

Safety note: use stable mounting, avoid sudden release of weights, and keep hands clear of falling hangers and moving pulleys during the experiment.

Care & Maintenance

• Store pulleys, strings, and weights together after each practical session.
• Check that pulley wheels rotate freely before use.
• Replace frayed strings or bent hooks to maintain reliable force alignment.
• Keep the board dry and flat to support accurate marking and drawing.
