Question

Explain how the amount of pressure created by a smaller piston can be the same as the pressure created by a larger piston?

Answer 1

I suppose we are using part of Pascal's Law.
\[Pressure = \frac{Force}{Area}\]

So, we're trying to make two differently sized pistons create the same pressure.

Pressure is inversely proportional to area.
So, at constant pressure, if the area of the surface increases, the pressure applied decreases.

That might be enough information to help you out. :3
