The given Hooke’s Law Apparatus is a simple yet essential physics laboratory instrument used to verify the relationship between applied load and extension in a spring. It helps students clearly understand the concept of elasticity and the behavior of a spring within its elastic limit.

 The apparatus is designed with a sturdy metal rod mounted on a stable base. A vertically adjustable scale graduated from 0 to 15 cm is provided for accurate measurement. A spring is suspended from an adjustable collar positioned above the scale, while the lower end of the spring is fitted with an integrated mass hanger and pointer to measure extension precisely as load is applied.

This apparatus is ideal for schools, colleges, and educational laboratories for demonstrating Hooke’s Law, spring extension, and elastic properties of materials in a practical and easy-to-understand manner.

 Experimental Objectives

To verify Hooke’s Law by studying the relation between load and extension of a spring.

To determine the spring constant of a given spring.
To understand elastic limit and spring behavior under different loads.
