A fundamental type of periodic motion in which an object moves back and forth through a central equilibrium point. The acceleration of the mass is always directed toward the center and is proportional to how far it has moved away. It serves as the baseline mathematical model for analyzing vibrations in springs, pendulums, and acoustic systems.

We can model the initial vibration of the beam as simple harmonic motion to find the natural frequency.
