When considering the operation of a double acting cylinder, particularly in the retracting phase, it's essential to understand how pressure works on the surfaces of the cylinder. The net area is crucial for determining the effective force generated by the cylinder when it's retracting.

In the context of this question, the net area is calculated by subtracting the area of the cylinder rod from the piston area. The piston area represents the total surface area that is available for pressure to act on when the piston is moving. When the cylinder retracts, the pressure acts on the entire piston, but part of that pressure must counteract the area of the rod, which occupies some of the space inside the cylinder.

Thus, for accurate calculations of force and performance, subtracting the rod area from the piston area gives the net effective area on which the pressure can act during retraction. This net area directly influences the cylinder's efficiency and force output, making it vital for pneumatic system design and operation.
