**Spring Mass System**

To determine the damping coefficient of a single-degree of freedom system.

**The experimental set up consists of **

- Spring Mass Test rig- with frame, Mass and Spring.
- Accelerometer.
- Signal Conditioner.
- Computer based data acquisition system

**Purpose: **To Estimate of Damping Ratio:

The logarithmic decrement is estimated from the expression

Ϭ= (1/n) log (A_{1}/A_{n})

Damping ratio ε= / (2π)
