Spring-Coupled Physical Pendula
Purpose
To demonstrate resonance and normal modes.
Equipment
Mounted spring-coupled physical pendula.

Description
After starting one of the pendula into motion in the plane of the picture, the motion couples back and forth between the two physical pendula at a rate determined by the spring constant and its location. Coupling can be varied by sliding the spring clamps along the pendula shafts. Normal modes can be nicely demonstrated.
