The research results on the derivation of equations motion (a mathematical model) a mechanical system constrained by holonomic constraints first and second kind, which contains only tangential components constraint are presented in article. These taken as control parameters. Besides, controllability plate, considered Appel problem, is investigated.

the sustainability of the built environment is increasingly coming to the forefront of infrastructure design and maintenance decisions. to address this, development of a new class of more sustainable cement-based materials is needed. fiber reinforced self-consolidating mortar (frscm) was developed by optimizing the micromechanical parameters, which control composite properties in the hardened s...
