How would you describe the piston surface area of a single rod double acting piston?

In a single rod double acting piston, the piston is designed to have differing surface areas on each side. This is primarily due to the rod that extends from one side of the piston. The area where the rod is attached reduces the effective surface area on that side compared to the opposite side, which is fully exposed. As a result, the side with the rod has less piston surface area available for pressure application than the side without the rod.

This design is integral to the operation of double acting pistons as it influences the force generated during the piston’s extension and retraction. The unequal areas enable the system to optimize performance in various applications, allowing for different forces to be exerted based on the pressure applied, which is essential for effective operation in hydraulic systems.
