In the context of pneumatic systems, what is the function of a cylinder?

In pneumatic systems, the function of a cylinder is to convert air pressure into linear motion. This is achieved through the use of compressed air that acts upon a piston within the cylinder. When compressed air is admitted into the cylinder, it creates a pressure differential that pushes the piston back and forth. As a result, the linear motion produced can then be harnessed to perform various mechanical tasks such as moving a load, driving machinery, or operating a tool. This conversion of energy allows for precise control of motion and force, making cylinders a fundamental component in pneumatic systems.

The other options do not accurately represent the primary function of a cylinder in this context. Generating high pressure and acting as a storage container for air are functions more associated with compressors and tanks, while measuring air flow rate pertains to flow meters rather than the function of a cylinder.
