  1. I think instead of shear sheer strength, you mean friction coefficient. Shear is the force perpendiculair to a plane But how easily things slide past each other is the field of Tribology. Shear strengt is a material property, that yes could be regarded as the viscosity of a solid, but it's within the object. 2 objects rubbing together experience friction, which is dictates by hardness, surface roughness, lubrication, normal force etc. Not the shear strenght of the material.
