Question: In a hydraulic system, if a small force is applied to a small piston, how does the pressure transmitted to a larger piston compare?
Answer options:
- The pressure is greater on the larger piston.
- The pressure is less on the larger piston. ✅ The pressure is the same on both pistons.
- The pressure depends on the fluid's viscosity.
Correct answer: The pressure is the same on both pistons.
Explanation: According to Pascal's Principle, pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. Therefore, the pressure is constant throughout the hydraulic system.
