中文导读
1937 年由通用汽车（GM）制作的经典工业科普老片。从两辆木轮推车转弯的第一性原理出发，一步步添加齿轮、剖面演示，条理清晰地讲透汽车差速器如何实现左右轮以不同转速平稳过弯。
为什么 HN 推它
被工科界与教育界反复传颂的教学奇迹。无需任何现代复杂特效，仅凭无懈可击的递进逻辑就达到了差速器原理解释的巅峰。
「这部拍摄于 1937 年解释差速器的短片，堪称教学设计上的奇迹。」HN 网友原话：this video explaining differentials is from 1937 and is a marvel of pedagogy
英文原摘要（HackerTube / Claude 整理）
A 1937 GM-produced film explaining how the automobile differential lets wheels turn at different speeds around a corner. It uses clear animations and cutaway demonstrations to build the idea from first principles.
Held up as a marvel of pedagogy and the best explanation of differentials, recommended again and again.
HN 上的提及
This 1937 video about differentials is also enlightening
is a great example of this.
There's also a great video from 1937(!) that shows why we need differentials, and how they work.
Heres a couple of others that I like. Differential Steering
Classic video about differentials from 1937 (!)
