# Lowest Spring Resonant Frequency Calculator

The natural frequency of a simple mechanical system consisting of a weight suspended by a spring is 1/2√(K/M) where M is the mass and K is the spring constant. A swing set is a simple example of a resonant system. Make use of this online lowest spring resonant Frequency calculator to determine the frequency of lowest spring resonance given the spring constant and mass of the spring as the inputs. Calculate the number of occurrences per unit time using the simple tool.

### Example:

Consider the spring constant K is given as 89, and the mass of the spring M is given as 45. Calculate the frequency of the lowest spring resonance?

#### Solution:

F(res) = 1/2√(K/M)

= 1/2√(89/45)

= 703.1674Hz.
