Solving Problems in Mechanics by Mechanical and Geometrical Considerations

Abstract: One of the problems that are solved with Statistics, as division of theoretical Mechanics, is the equilibrium of the system of forces in which the conditions are determined for a system of forces to be in equilibrium. In classical mechanics, the state of equilibrium of a material body can be defined from static or dynamic point of view, both being forms of mechanic equilibrium. Mechanics depends on mathematics, in the sense that almost no problem of mechanics can be solved without mathematics. Thus, interdisciplinarity being the cooperation between various disciplines from the same curricular area, it means that the approach has as its aim forming a unitary image regarding a certain theme. This implies the combination of two or several academic disciplines in one single activity, thus simultaneously accumulating new knowledge in several domains. In this context, the paper presents aspects on solving problems of equilibrium of rigid bodies, by mechanical and geometrical considerations, namely with the condition of concurrency of three lines in a plane.
