[Setup Time: 15 Min.] [Current Condition: Good]
Same as 3A70.1 Spring-Coupled Pendula. This time, however, observe the two normal modes by a) releasing both pendula from the same side or b) releasing them from opposite sides. There's a slight shift in the resonance frequency- detecting this small change is the basis of how an atomic force microscope (AFM) works, for example.
2 Pendula connected with Springs mounted on Stands in C. Oscillations, 1B
