The formula to calculate the belt tension frequency (f) is:
\[ f = \sqrt{\frac{T}{4 \cdot m \cdot L^2}} \]
Where:
Let's say the tension (T) is 100 N, the mass (m) is 0.5 kg, and the length (L) is 2 m. Using the formula:
\[ f = \sqrt{\frac{100}{4 \cdot 0.5 \cdot 2^2}} \]
We get:
\[ f \approx 5 \, \text{Hz} \]
So, the belt tension frequency is approximately 5 Hz.
