Equal-sized cylinders will not operate in synchronization because of ___________.

Equal-sized cylinders will not operate in synchronization because of ___________.

• A. Unequal loading
• B. Fluid compressibility
• C. High pressure
• D. Temperature variations

Answer: (A)

Equal-sized cylinders will only stay in step when the resisting forces on each piston are the same. If the loads are different, the cylinder facing the lighter load needs less hydraulic force to move and will take a larger share of the available flow from the pump. The heavier-loaded side then gets less flow or must wait for higher pressure, so its movement lags. Because both cylinders share the same hydraulic supply, flow splits according to resistance, not equally, leading to unequal speeds and a lack of synchronization. Other factors like fluid compressibility, high pressure, or temperature variations can affect motion timing or friction slightly, but they don’t cause synchronization to fail on their own—the unequal external loading is the primary reason.
