Second Overtone Frequency Solution

Follow our step by step solution on how to calculate Second Overtone Frequency?

FIRST Step Consider the formula

v 0->3 = (3 \cdot v vib) \cdot (1 - 4 \cdot x e)

Next Step Substitute values of Variables

∴

v 0->3 = (3 \cdot 1.3Hz) \cdot (1 - 4 \cdot 0.24)

Next Step Prepare to Evaluate

∴

v 0->3 = (3 \cdot 1.3) \cdot (1 - 4 \cdot 0.24)

LAST Step Evaluate

∴

v 0->3 = 0.156Hz
