The principle of virtual velocities,by the displacement of its application point, named virtual velocity. He offers a number of applications to the various cases including the fluid but does not provide any demonstration. In the final part a comparison of Varignon’s mechanics, based on composition of forces and Bernoulli’s mechanics based on his VWL is considered.作者: Culpable 時間: 2025-3-22 03:36
,The debate at the école polytechnique,Ampère is presented. Note the use of purely geometric virtual velocities, following the lead of Lazare Carnot. In the third part the probably less interesting demonstration of Pierre Simon Laplace is reported.作者: milligram 時間: 2025-3-22 07:56
Logic status of virtual work laws, intuitive nature of evidence, possibly established a priori. Currently there is a more liberal view and one does not require evidence of the principles, only that they must have sufficient strength and do not lead to logical contradictions.作者: Archipelago 時間: 2025-3-22 11:49 作者: 羅盤 時間: 2025-3-22 16:40
Introduction,forces appear together with the motion of their points of application independently of the logical status assumed, be it a theorem, a principle or an empirical law. In this sense the . of virtual work represent a particular historical point of view on mechanics.作者: abysmal 時間: 2025-3-22 17:44 作者: crescendo 時間: 2025-3-22 22:33
,Lazare Carnot’s mechanics of collision,ulating a generalization of VWL that allows one to evaluate the velocities of a system of hard bodies each of which the initial velocity is known. In the second part his extension to gradually variable forces is presented with the introduction of virtual or real work, named moment of activity, as the fundamental magnitudes of applied mechanics.作者: Inferior 時間: 2025-3-23 04:30 作者: Inexorable 時間: 2025-3-23 08:46 作者: 在前面 時間: 2025-3-23 13:37

Thermodynamical approach,This chapter is devoted to the use of the VWL where to virtual work is given a mechanical meaning. In the first part, notes on mechanics derived from Pierre Duhem’s thermodynamics are presented. In the second part the derivation of a VWL from the law of conservation of energy is shown.作者: Cloudburst 時間: 2025-3-25 05:48
