PickVidsAn elevator that actually goes sideways
推荐理由
Here's a tour of the system in their test tower by Tom Scott
说明
这是2017年由Tom Scott发布的一部讲解，主题归在Mechanical & precision engineering。它讲的是rope-free elevators这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：Tom Scott visits ThyssenKrupp's test tower in Rottweil to see the Multi, a rope-free elevator that uses linear motors to move cabins sideways as well as vertically.这些读者给出的理由，核心是：HN links it whenever ThyssenKrupp's Multi or paternoster lifts come up, as the clearest look at the working test tower.讲法不绑某一条新闻，过几年仍然可以当材料看。从2017年到2021年，有0位不同的读者在0个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比，比背公式重要。如果已经会了基本定义，就把注意力放在它怎么把rope-free elevators变成能跟着复述的例子。
