**Transcription:**

In a double-acting, single-rod cylinder, why is the force greater on the extend stroke than the retract stroke?

**Explanation of Diagram:**

The diagram depicts a simple schematic of a double-acting, single-rod cylinder. It illustrates the cylinder with an extending rod moving in the direction indicated by an arrow labeled "Extend." 

The concept behind the greater force on the extend stroke is due to the effective area available for pressure application. During extension, the entire cross-sectional area of the piston is exposed to the pressurized fluid. In contrast, on the retract stroke, the rod takes up some of the area, reducing the effective pressure area, and thus the force exerted is less compared to the extend stroke.
