And so what happens when we remove these stops is that the piston slams up against the next pair of stops.

把挡板移开后活塞会,向上移动直道第二个挡板处。

So we remove the stops, and the piston moves up, and now we remove one of these weights.

我们移走挡板，活塞向上移动，移走一个重物。

Pistons in the car, right, so the piston goes up.

Then I'm going to release these little pegs here and my piston is going to shoot up now p1 because p2 is less than p1.

现在移开插销,活塞就会往上冲,因为p2小于。
