Bending of Beam Apparatus, Koenig’s Method

Product Code : LSK-AM-11095

Bending of Beam Apparatus, Koenig’s Method (SKU LSK-AM-11095) finds Young's modulus of a brass beam by an optical lever: two tilting mirrors turn slightly as the loaded beam bends, magnifying a very small deflection. It is used for the Koenig's method practical in B.Sc. physics and engineering physics labs. Production takes place in the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the company supplies colleges, schools, tender contractors and distributors directly.

Specifications

A one metre brass beam of 9 mm square section rests on the knife edges of two heavy table clamps. A sharp knife edge with hanger sits on the beam to take the load, and two tilting mirrors are provided to register the change in slope of the beam as it bends.

Applications and Experiments for the Koenig's Method Apparatus

In Koenig's method mirrors attached to the beam tilt as it bends, and the shift of a scale image seen by reflection gives the tiny change in slope. Students use it to determine Young's modulus of brass in B.Sc. physics and engineering physics elasticity practicals, where direct depression readings would be too small.

• B.Sc. physics: Young's modulus of a beam by Koenig's optical lever method.
• Illustrating how a mirror magnifies a small angular deflection.
• Engineering physics: relating beam curvature to load and section size.

Standard Scope of Supply

Each set includes the 1 m brass beam, two heavy table clamps with knife edges, the knife edge with hanger, and two tilting mirrors. It can be ordered with or without weights. A reading telescope and scale are not among the listed contents and can be requested on the quotation if needed.

Packing, MOQ and Lead Time

You are welcome to ask for a price on one set or on a quantity for a full practical class. Science Lab Supplies replies with a quotation giving packing, delivery time and price for that number, and other school physics lab equipment in India can be priced on the same document.

Backed by an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. The enquiry cart collects the items you want priced, the contact page handles questions, and the lab tender page covers tender purchases.

Frequently Asked Questions

How is Koenig's method different from the plain bending of beam method?
Instead of reading the central depression directly, Koenig's method reads the tilt of two mirrors attached to the beam. This optical lever magnifies a very small deflection, so a stiff 9 mm brass beam can be tested.

What beam is supplied?
The apparatus comes with a brass beam of 9 mm square section and one metre length, resting on the knife edges of two heavy table clamps with a knife edge and hanger for the load.

Can it be ordered without weights?
Yes. The set is offered with or without weights, so a lab that already has a slotted mass set can order the apparatus alone and list only the items it actually needs.

Does Science Lab Supplies produce this apparatus itself?
It does. The Koenig's method set is made on the company's own shop floor in Saha, Ambala, India, and buyers are quoted by the manufacturer instead of an agent.

Related Elasticity Apparatus

These items share the elasticity practical list with Koenig's method. Together they give a direct bending method, a cantilever method, a rigidity experiment and a mass set, so a department can compare elastic constants by several routes and place all of them on a single quotation.
