Let's start by seeing if I understand the mechanism as discussed for liquids. I'll first discuss the solid analogy (the deck of cards) to see if I get that. Let's suppose we do the above sliding plate experiment with thin sheets of solid material (we can consider our sheets and plates to be...

Indeed, but resist how? That's the mechanism I'm trying to understand better. Perhaps it would be better if I asked in terms of force or energy. If I apply shear stress to a solid (if I correctly understand elastic deformation), it generates a force counter to the applied force because some...

I'm trying to get a better handle on the actual physical phenomena underlying viscosity (for Newtonian fluids). Something I could word in the format of "this happens (and this and this), and so the fluid resists flow." What I've found online is that when gasses are at higher temperatures, they...
