Best Mechanical & precision engineering Videos
「Mechanical & precision engineering」下面有141部被不同的人、在不同月份推荐过的视频。挑的时候先看对象:入门8部,适合还没学过的人;进阶22部,适合已经懂术语的人;普通向106部,按兴趣就能看;更硬的5部,留给想看推导或细节的人。这一类数量最多的是演示,所以它们的共同点是先看到做成了什么,再决定要不要追细节。常出现的频道包括Technology Connections、Veritasium、Stuff Made Here。目录给这个主题划的范围是:Mechanical engineering: machines, mechanisms, gears, precision design, flexures, hydraulics, thermodynamic machines, engineering failures, clever mechanical designs, how it works explainers.如果只看三部,就从《Around The Corner - How Differential Steering Works (1937)》开始,它负责把问题讲出画面;然后看《Detergent packs are kinda wishy-washy (Dishwashers Explained)》,换一种讲法或例子;最后看《Mechanical Computer (All Parts) - Basic Mechanisms In Fire Control Computers》,留给已经有基础的人。页面按每页24部切开,顺序看的是被推荐跨越了多少个月,不是播放量。每条标题下面那一句是这部片子自己的内容说明,用来区分它在讲定义、过程、演示还是观点。点进去能看到推荐原话、原文链接和适合谁看。看的时候把强烈推荐当成有人明确叫你去看,把引用当成只是拿来举例,把批评留下来对照,不要把每条评论都当成同一力度。
