固体对其它物体会产生压力.固体产生的压力方向是单一的.受力面若水平,压力方向竖直向下,若受力面不水平,则压力方向与受力面垂直,是斜向下.液体、气体因具有流动性.它们产生的压强与固体不同.在一个放于水平面上的魔王形容器中,分别装入固体(干的细砂类除外)、液体和气体时,器底受到的压力都等于容器中物体的重力,但液体、气 Solids will generate pressure on other objects. The pressure generated by the solid is in one direction. If the force surface is horizontal, the pressure direction is straight downward. If the force surface is not horizontal, the pressure direction is perpendicular to the force surface, and it is inclined downwards. Liquids and gases are fluid. They produce different pressures than solids. In a devil-shaped container placed on a horizontal surface, when solids (except fine dry sand), liquids, and gases are introduced into the container, the bottom is affected. The pressure is equal to the gravity of the object in the container, but the liquid and gas
