| Outline of Final Research Achievements |
We focused on a pinning effect of contact line on sliding friction by liquid bridge. A force during sheared process of a liquid bridge between parallel plates was measured. Behavior of contact lines was also observed.
Combination of rougher surfaces results in larger pinning effect and larger sliding friction. We also found that slippage at liquid-solid interface is initiated by inertial effect. Roughness on the non-driving plate has larger effect on sliding force.
