This moment quantity of Mechanical platforms, Classical Models, offers with the dynamics of platforms which includes discrete debris in addition to non-stop platforms. whereas modifications among those types are highlighted, the generality of the proofs and corresponding computations yields effects which are expressed in a typical shape for either discrete and non-stop platforms. the writer explains intimately all vital elements of the technology of mechanics, considered as a normal technological know-how, and exhibits how they're important in figuring out very important typical phenomena and fixing difficulties of curiosity in utilized and engineering sciences. a wide number of difficulties are analyzed, from the conventional to newer ones, similar to the dynamics of inflexible solids with variable mass. Professor Teodorescu has spent extra that 50 years as a Professor of Mechanics on the college of Bucharest and this ebook depends upon the vast literature at the topic in addition to the author's unique contributions.
Audience: scholars and researchers in utilized arithmetic, physics, chemistry, mechanical engineering.

3. 24' (theorem of torsor; second form). The motion of a discrete mechanical system subjected to constraints takes place so that, at any moment, the sum of the torsor of the lost forces of d’Alembert with respect to a fixed pole and the torsor of the constraint external forces with respect to the same pole vanishes. 36) vanishes). 63) which represents a necessary condition to describe the motion. , m are non-determinate scalars (Lagrange’s multipliers) and where we noticed that in a finite double sum one can invert the order of summation.
For instance, a man (in general, a living being) in a vertical position on a perfect smooth ground cannot rotate about a vertical axis passing through its centre of mass (he is acted upon only by his own weight and by the normal constraint force of the ground, the resultant moment of the external forces with respect to the centre of mass vanishing). The rotation takes place only if a pivoting friction between man and ground intervene too (as in case of walking) or by various complicated motions made by the man, as we will see later.
6 Conservation Theorems of Moment of Momentum. Theorem of Areas. Applications If the moment MO of the given external forces is contained in a fixed plane (is normal to a fixed axis Δ, O ∈ Δ , of unit vector u, with respect to the frame of reference R or has a zero component, MO ⋅ u = 0 ), as in the case of a single particle (see Chap. 6, Sect. 31) obtaining thus a scalar first integral of the equations of motion; in this case, the projection of the moment of momentum KO on the axis Δ is conserved in time.
