مسئلہ 4۔ Wobbly bridge

بیان

A horizontal metal ruler extends into the air and is supported just at one end, like a cantilever bridge. A plastic cup is attached to the other end of the ruler. Water droplets fall into the cup from a dropper at regular time intervals. Motionless at first, the bridge starts oscillating up and down, and then again comes to rest. Investigate and explain this effect.
