In a hydraulic system, when the pressure is increased in one piston, what happens to the pressure in the connected piston?

• A. It decreases
• B. It remains the same
• C. It increases
• D. It becomes irrelevant

Answer: (C)

In a hydraulic system, when pressure is increased in one piston, the principle of Pascal's law applies, which states that a change in pressure applied to a confined fluid is transmitted undiminished throughout the fluid in all directions. Therefore, when the pressure in one piston increases, the same increase in pressure is transmitted to the connected piston. This means that the pressure in the connected piston will also increase. The fluid in the hydraulic system acts as a medium that allows for pressure changes to be communicated effectively. This is why the correct answer is that the pressure in the connected piston increases alongside the pressure applied to the first piston.
