 note = {We perform a static analysis of a circular cylinder that forms a barrier between　surfactant-laden and surfactant-free portions of a liquid–gas interface. In addition　to determining the general implications of the balances for forces and torques, we quantify how the imbalance ∆γ=γ_α-γ_b between the uniform surface tension γ_a of the surfactant-free portion of the interface and the uniform surface tension γ_b of the surfactant-laden portion of the interface influences the load-bearing capacity of a hydrophobic cylinder. Moreover, we demonstrate that the difference between surface tensions on either side of a cylinder with a cross-section of arbitrary shape induces a horizontal force component f^h equal to ∆γ in magnitude, when measured per unit length of the cylinder. With an energetic argument, we show that this relation also applies to a rod like barrier with cross-sections of variable shape. In addition, we apply our analysis to amphiphilic Janus cylinders and we discuss practical implications of our findings for Marangoni propulsion and surface pressure measurements.},
