Enter the spring constant (N-m) and the mass (kg) into the Damping Ratio Calculator. The calculator will evaluate and display the Damping Ratio.

## Damping Ratio Formula

The following formula is used to calculate the Damping Ratio.

DMP = 2* SQRT(k*m)
• Where DMP is the Damping Ratio ( )
• k is the spring constant (N-m)
• m is the mass (kg)

To calculate the damping ratio, take the square root of the product of the spring constant and mass, then multiply the result by 2.

## How to Calculate Damping Ratio?

The following example problems outline how to calculate Damping Ratio.

Example Problem #1:

1. First, determine the spring constant (N-m).
• The spring constant (N-m) is given as: 3.
2. Next, determine the mass (kg).
• The mass (kg) is provided as: 5.
3. Finally, calculate the Damping Ratio using the equation above:

DMP = 2* SQRT(k*m)

The values given above are inserted into the equation below and the solution is calculated:

DMP = 2* sqrt(3*5) = 7.749

Example Problem #2:

For this problem, the variables required are provided below:

spring constant (N-m) = 6

mass (kg) = 7
