I've read in places that fluids cannot sustain tangential force acting on them. However when reading about surface tension I read the following paragraph on wikipedia
There are two primary mechanisms in play. One is an inward force on the surface molecules causing the liquid to contract. Second is a tangential force parallel to the surface of the liquid. This tangential force (per unit length) is generally referred to as the surface tension.
This paragraph clearly mentioned that surface tension is acting tangential force to the surface of the liquid, but it contradicts with the theory above. How is that possible?
Also if it is the result of cohesive and adhesive forces why does it act tangentially to the surface of liquid?
