Demo Number 275
Location Shelf 48
Description The mass hanging from the spring demonstrates a coupled oscillator system. The spring and the mass are designed so energy and oscillatory motion are transferred back and forth between the up and down oscillation of the spring and the rotational motion of the mass.

  • The adjustable weights on the bob are used to tune its moment of inertia. The spring has strongly coupled oscillation modes: a translational mode – up and down, and a rotational mode. At resonance the two modes alternate, giving one point of pure translation and one point of pure rotation. Lock pendulum holder in a clamp VERTICALLY ONLY to support the spring without damaging it.
  • You will need a tall lab stand.
