As a result, one side of the fault area lifts, causing the pressure that has been building up inside to be released.

So the force that you're pushing down on here is the external pressure times the area.

或者压缩功的概念,在活塞上施加压力。

The piston has a cross-sectional area, a, and the force pressure is force per volume area.

我们以活塞系统为例，来说明膨胀功。

We know the pressure is equal to force per area.

我们知道压强等于力除以面积。
