帕斯卡在1648年表演了一个著名的实验:他在一个密闭的装满水的水桶盖上插入一根细长的管子,从楼房的阳台上向细管子里灌水,结果只用了几杯水,就把桶压裂了,桶里的水就从裂缝中流了出来.这就是历史上有名的帕斯卡裂桶实验.一个容器里的液体,对容器底部(或侧壁)产生的压力远大于液体自身所受的重力,这在许多人看来好像是不可思议的,我们可以用液体压强的知识来解释裂桶实验.探究液体压强的特点压强即物体所受压力的大小与受力面积之比,用来表示压力的作用效果.固体作用于其他物体的压强 Pascal performed a famous experiment in 1648: he inserted a slender tube into a closed, water-filled bucket lid and poured it into the thin tube from the balcony of the building, using only a few glasses of water, This is the well-known Pascal split barrel experiment in which the liquid in a container exerts a much greater pressure on the bottom (or sidewall) of the container than in the liquid itself The gravity, which seems to many people seems weird, we can use the liquid pressure of knowledge to explain the crack bucket experiment.Check the characteristics of the pressure of the liquid pressure that the pressure of the object by the size of the area under stress, with To show the effect of pressure, the pressure exerted by the solid on other objects
