A rattleback is a semi-ellipsoidal top which will rotate on its axis in a preferred direction. If spun in the opposite direction, it becomes unstable, "rattles" to a stop and reverses its spin to the …

Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin (i.e., a spin-bias). If spun in one direction, the rattleback will exhibit seemingly stable rotary motion. If spun in the …

The rattleback is a great example of physics at work and the complexities of describing what appears to be a simple toy. Researchers have worked over decades to describe the motion of …

How Does a Rattleback Work? A quick explanation for the classic physics toy, the Rattleback™. The Rattleback takes the shape of an elongated asymmetrical semi-ellipsoid – a squashed …

2019年9月1日 · Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin (i.e., a spin-bias). If spun in one direction, the rattleback will exhibit seemingly stable rotary motion. If …

2017年9月12日 · The rattleback is a boat-shaped top with an asymmetric preference in spin. Its dynamics can be described by nonlinearly coupled pitching, rolling, and spinning modes.

A rattleback is an object that rotates in only one direction. If you try to rotate it in the "wrong" direction, it stops and begins rotating in the other direction.

2020年8月1日 · The rattleback, also known as the celtic stone (or simply, the celt), is a rigid semi-ellipsoidal (canoe shape) object which exhibits rotational preference. More precisely, when …

2019年1月15日 · Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin. If spun in, say, the clockwise direction, the rattleback will exhibit stable rotary motion. If spun in …

2014年7月1日 · A rattleback is a canoe-shaped body that, when spun on a smooth surface, rotates stably in one direction only; when spun in the reverse direction it oscillates violently …
