关节玩具的物理学-跳跃和旋转的袋鼠
The physics of articulated toys - a jumping and rotating kangaroo
摘要：
我们描述了一个由螺旋弹簧提供内部能源的铰接玩具的物理学。玩具是一个有趣的低成本袋鼠跳跃和旋转。研究包括力学和热力学分析，它利用牛顿和质心方程，转动方程和热力学热力学第一定律。这个令人惊奇的玩具提供了一个很好的示范性例子，说明当在机械系统的研究中建立与热力学的联系时，如何带来新的物理学见解。
英文摘要：
We describe the physics of an articulated toy with an internal source of energy provided by a spiral spring. The toy is a funny low cost kangaroo which jumps and rotates. The study consists of a mechanical and a thermodynamical analysis which makes use of the Newton and center of mass equations, the rotational equations and the first law of thermodynamics. This amazing toy provides a nice demonstrative example how new physics insights can be brought about when links with thermodynamics are established in the study of mechanical systems.
