Two cylinders are connected by a piston, as shown in Fig. $\mathrm{P} 1.100 .$ Cylinder $A$ is used as a hydraulic lift and pumped up to $500 \mathrm{kPa}$. The piston mass is $25 \mathrm{~kg},$ and there is standard gravity. What is the gas pressure in cylinder $B$ ?

Key Concepts

Pascal's Principle

Pascal's Principle states that a change in pressure applied to an enclosed fluid is transmitted uniformly in all directions throughout the fluid. This concept is central to understanding how forces are distributed and multiplied in hydraulic systems, such as lifts or brakes.

Pressure as Force per Unit Area

Pressure is defined as the force acting per unit area. This relationship is fundamental in fluid mechanics, allowing the determination of forces acting on surfaces when the pressure and area are known, independent of the specific fluid or system configuration.

Force Equilibrium

Force equilibrium is the condition where the sum of forces acting on a system is zero, resulting in a static or balanced state. In hydraulic systems, equilibrium analysis is used to balance forces generated by fluid pressures with external forces such as weights or gravitational forces.

Hydraulic Systems

Hydraulic systems utilize fluids under pressure to transmit and amplify force. By applying a small force over a small area, a hydraulic system can generate a larger force over a larger area, making them effective for lifting heavy loads and for applications requiring precise force control.
