... Answer: This is the mathematical expression for the equilibrium rule, which states that the vector sum of the forces acting on an object is equal to zero if that object is in a state of rest, or a state of unchanging velocity. "Vector sum" means that direction is vital. If for example, an object is ...

... on B. In that case, C is given by the elastic constants of A at the interface (7], hence cannot be changed independently. Since c is rather large in many materials, zero friction should be observed for moderate applied loads in the absence of wear and plastic deformations. For a multiatom «tip» whic ...
