The natural frequency of this dowel rod is determined as 0.5 Hz.
<h3>What is frequency?</h3>
The frequency of an object is the number of complete revolutions per second.
F = n/t
where;
- n is number of compete revolution
- t is time
F = 1/2
F = 0.5 Hz
Thus, the natural frequency of this dowel rod is determined as 0.5 Hz.
