Parallelogram Force Apparatus

Product Code : LSK-AM-11103

Parallelogram Force Apparatus (SKU LSK-AM-11103) is used to verify the parallelogram law of forces by balancing three forces at a point and drawing them to scale on a board. Built on 12 mm thick plywood, this model follows the wall type but is meant for laboratories where wall space is limited. It suits Class 9 to 11 physics and introductory engineering mechanics. Science Lab Supplies produces it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies schools, colleges, contractors and distributors from the factory.

Specifications

The apparatus is built on a thick plywood piece, 12 mm in thickness. Its design is similar to the wall-mounted parallelogram of forces apparatus, but this version is intended for laboratories where wall space is limited, so it does not depend on a free wall for mounting.

Applications and Experiments for the Parallelogram Force Apparatus

The apparatus shows that when two forces act at a point, their resultant is given by the diagonal of the parallelogram drawn with the two forces as adjacent sides. It supports the Class 11 vectors topic, the parallelogram law activity in school physics and statics practicals in diploma and first-year engineering mechanics.

• Class 11 physics: verifying the parallelogram law of vector addition using forces.
• Finding the weight of an unknown body using the parallelogram law.
• Engineering mechanics: equilibrium of three concurrent forces and Lami's theorem.

Standard Scope of Supply

The Parallelogram Force Apparatus is supplied as a single unit as described above, built on the 12 mm plywood board. Any optional accessories, such as a set of masses and hangers, are listed on the quotation, so tell us what your practical requires when you make an enquiry.

Packing, MOQ and Lead Time

Ask for a quotation for one apparatus or for a quantity that covers each group in your lab. Every quotation lists packing, delivery time and price for that number, and a mass set or other mechanics lab equipment in India from the Applied Mechanics range can be added to it.

Holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. To enquire, open the contact page or the enquiry cart; institutional buyers can also use the lab tender page.

Frequently Asked Questions

What law does the Parallelogram Force Apparatus verify?
It verifies the parallelogram law of forces: if two forces acting at a point are drawn as adjacent sides of a parallelogram, the diagonal from that point gives their resultant in size and direction.

How is this model different from the wall type?
It is similar to the wall-type apparatus but is intended for laboratories where wall space is limited, so the board does not need to be fixed to a wall before use.

Where can I confirm the board size and fittings?
Ask through the contact page and Science Lab Supplies will send the board dimensions, fittings and any masses that can be included, together with the quotation for your quantity.

Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The apparatus is made at the Science Lab Supplies factory in Saha, Ambala, India, and you receive the quotation from the maker rather than a middleman.
