The rod side area that produces the pull force on a double-acting cylinder is called the _____ area.

Explanation:
The rod side area is the annular area around the piston rod. Because the rod occupies part of the bore, the hydraulic fluid on the rod side only acts on this ring-shaped region, not the full circular piston face. That’s why the pull force on the rod side is determined by the annular area, not the full piston area. The force equals pressure times this annular area, A_annular = (π/4)(D^2 − d^2), where D is the bore diameter and d is the rod diameter.
