A question on understanding the nature of static equilibrium

In Engineering, we are usually not concerned with the detailed molecular level of material behavior. That is the job of material scientists and engineers. We assume a point load on a slab or on top ...

A question on understanding the nature of static equilibrium

What you describe in your first example is perfectly covered by usual engineering calculations and is described by the Poisson effect. When you squish a solid (in this case, by its own weight) said ...
