Brush car NO.1 is a magical car, do not underestimate this set of experimental materials. Ordinary small brush, in the hands of the children will become magical, and increase their curiosity and thinking habits. Helps in teaching the concept of vibration, eccentric wheel shaft and motors.
working: Eccentric wheel: The so-called eccentric wheel means that the axis of the wheel is not on the center of the wheel. At this time, the wheels are not on the same plane when they move, which causes the object to vibrate. Eccentric vibration: This term is often used in cell phone vibrators and is caused by the eccentric rotation of a metal rod. Due to the high-speed rotation inside the sealed metal box where the metal rods are located, the internal air of the metal box also undergoes violent movement by friction. This causes the entire sealed metal box to vibrate, which in turn drives the entire mobile phone to vibrate.
