Disney tops and yo-yos with stable spins despite asymmetric shapes
Zurich, Switzerland (SPX) Aug 21, 2014 - Tops and yo-yos are among the oldest types of playthings but researchers at Disney Research Zurich and ETH Zurich have given them a new spin with an algorithm that makes it easier to design these toys so that they have asymmetric shapes. The algorithm can take a 3D model of an object and, within less than a minute, calculate how mass can be distributed within the object to enable a stable ... more
