Extracted text: XA P1= P2 R R Figure shows an example of a hydraulic accumulator, which is a device for reducing pressure fluctuations in a hydraulic line or pipe. The fluid density is p, the plate mass is negligible, and the plate area is A. All the given pressures are gauge pressures. Write down the equations of motion.
