Abstract

An application of the virtual displacements principle is considered in regard to three main cases, including systems with wall constraints, systems described with equation of motion possessing non-unique solutions, systems with discontinuous forces in equilibrium condition. Various equilibrium examples are presented for some special cases including non-regular point of constraint surface as well as non-analytical dependence force of position.
