一、固体和液体压强(一)固体产生的压力或压强思路与方法:由于压力是垂直作用于受力物体表面的力;固体有压强是相互接触的物体表面的相互挤压作用产生的.所以,解答此类问题时,通常要需要先根据题意找出题设条件直接给出的压力或根据题意计算出压力,分析找出物体的受力面积,然后利用 First, solid and liquid pressure (a) the pressure or pressure generated by the solid Ideas and methods: Because the pressure is a force acting perpendicular to the surface of the force object; solid pressure is generated by mutual extrusion of the surfaces of the objects in contact with each other. When answering such questions, it is usually necessary to first find out the pressure given directly by the conditions of the questions or calculate the pressure according to the questions according to the questions, analyze and find out the force area of ​​the objects, and then use.
