To determine the Young's Modulus of a Wire by Optical Lever Method
The Young’s Modulus of a Wire by Optical Lever Method Apparatus is a physics laboratory instrument designed to determine the Young’s modulus of the material of a wire by measuring its extension under an applied load using the optical lever technique. This method uses an optical lever and a scale with a suitable light source or telescope arrangement, depending on the model, to measure small changes in the length of the wire with improved sensitivity.
The apparatus demonstrates the relationship between applied force, extension, original length, and cross-sectional area of a wire. By recording the change in length for different loads and applying the formula for Young’s modulus, students can investigate the elastic properties and stiffness of the wire material.
Ideal for physics laboratories in colleges, universities, and engineering institutions, this apparatus provides practical experience in elasticity, optical measurement techniques, and experimental determination of the mechanical properties of materials.
