Description

A helical spring is a coiled mechanical device that stores and releases energy to absorb impacts or shock and to resist either compression or pulling forces between objects.

Spring constant is the restoring force per unit extension in the spring. Its value is determined by the elastic properties of the spring.

A given object is attached to the free end of a spring which is suspended from a rigid point support. If the object is pulled down and then released, it executes simple harmonic oscillations.

The effective mass of the spring in a spring-mass system when using an ideal spring of uniform linear density is 1/3 of the mass of the spring and is independent of the direction of the spring-mass system.

The time period (T) of oscillations of a helical spring of spring constant K is given by,

If spring has a large mass of its own,

And,

Hence, the spring constant,

The nature of graph of T2 against m is a straight line.
