The Bending of Beam Apparatus – Koenig’s Method is a precision laboratory setup used for determining the Young’s Modulus of a beam material by observing its deflection under applied load. This method provides accurate results by using optical measurement through mirror reflection and telescope observation.
The apparatus consists of a brass beam of approximately 1 meter length with a 9 mm square cross-section. The beam is supported horizontally on two knife edges fitted on cast iron G-clamps. A weight hanger is provided at the required position for applying load to the beam. Two adjustable plane mirrors mounted on the beam help in measuring the deflection with high sensitivity. The shift in the reflected image is observed through a reading telescope for precise calculation.
This apparatus is suitable for physics and engineering laboratories in schools, colleges, universities, and technical institutions for experiments related to elasticity, beam deflection, and material properties. Supplied without slotted weight set.
