水柱体重秤996views 汤圆儿圆 @ 19th. 06. 2011
设计师Jaeyoon Park, Dajeong Kim & Jeong Heo为了环保事业，特意设计制作了这款水柱体重秤。采用阿基米德定律，小编的物理一直不怎么好，各位物理达人来看看，当人站上去的时候，且不说是否平稳，陷下去的部分肯定只有一小部分，但阿基米德定律说当物体完全浸没在液体或气体时，V排=V物；但物体只有一部分浸入液体时，则V排<V物。这么说女士们站上去又可以得瑟啦？！物理达人，是这样吗？via：

这事跟阿基米德没关系，跟帕斯卡有关系

跟刻度间距和玻璃管的粗细有关，即系数X
V排×X=V物

帕斯卡原理，在封闭液体上施加的压强各向一致。
2楼说的也是错的，水柱产生的压强只跟水柱高度有关，与管子直径无关。
