A basic method of the derivation of equations of movement of as holonomic, as nonholonomic structures with the restrictions of any order is advised. The process of equations of movement within the generalized coordinates is considered a one vector relation, represented in an area tangential to a manifold of all attainable positions of process at given quick. The tangential house is partitioned by way of the equations of constraints into orthogonal subspaces. in a single of them for the limitations as much as the second one order, the movement low is given by way of the equations of constraints and within the different one for perfect constraints, it's defined via the vector equation with out reactions of connections. within the entire house the movement low contains Lagrangian multipliers. it truly is proven that for the holonomic and nonholonomic constraints as much as the second one order, those multipliers are available because the functionality of time, positions of approach, and its velocities. the appliance of Lagrangian multipliers for holonomic platforms allows us to build a brand new procedure for settling on the eigenfrequencies and eigenforms of oscillations of elastic platforms and likewise to signify a unique kind of equations for describing the procedure of movement of inflexible our bodies. The nonholonomic constraints, the order of that's more than , are considered as programming constraints such that their validity is supplied because of the life of generalized regulate forces, that are decided because the services of time. The closed procedure of differential equations, which makes it attainable to discover as those keep an eye on forces, because the generalized Lagrange coordinates, is compound. the idea steered is illustrated via the examples of a spacecraft movement. The e-book is essentially addressed to experts in analytic mechanics.
