Oscillating cart
Experiment no.: 5.3.101
A small cart and two steel springs form an oscillatory system. An electric motor with an eccentric mechanism periodically deflects the cart from its resting position. The drive frequency is steadily increased so that the system passes through the resonance curve. This experiment is particularly nice and highly recommended.
