The Flat Spiral Spring Apparatus is a practical physics laboratory instrument used to study the elastic behavior of a flat spiral spring and determine the Young’s Modulus of its material. It is designed for clear observation, balanced loading, and accurate measurement during elasticity experiments.
The apparatus consists of a flat spiral spring mounted on the upper end of a bracket attached to a vertical stand. The lower end of the spring is provided with an attachment carrying two graduated sliding weights fitted on a threaded screw, allowing controlled and balanced loading. A graduated scale marked from 0 to 7 cm is provided for measuring the extension of the spring during the experiment.
With its simple working design and stable arrangement, this apparatus is suitable for schools, colleges, universities, and educational physics laboratories.
Experimental Objectives
To determine the Young’s Modulus of the material of a flat spiral spring.
To study the elastic behavior of a flat spiral spring under load.
To measure the extension produced in the spring due to applied loading.
To understand the relationship between load, extension, and elastic properties of the material.
