Lecture

Torsion Pendulum and Internal Friction

Description

This lecture explores the dynamics of a torsion pendulum with internal friction, discussing the equations of motion, damping effects caused by crystal defects, and the concept of internal friction energy dissipation. The instructor also explains the relationship between frequency, relaxation time, and energy dissipation, illustrating how different frequencies affect the movement of crystal defects and lead to internal friction spectra.
