Please, say me what are shear forces. I've been looking for it because I was studying a phenomenon called hydraulic jump. In this example, are these forces caused by the cohesion forces?

I don't know any of this stuff myself, but I always sympathize with someone who has no resposes to a post. Maybe http://astron.berkeley.edu/~jrg/ay202/node17.html [Broken] can help?

A shear force per unit area (i.e, shear stress) acts tangential to a surface, rather than in the normal direction to the surface.

"Hydraulic jump?" You don't, by chance, mean hydraulic hammer?
