Application of AutoCAD for Graphic Solutions in Determining Static Quantities

Graphic images have accompanied the human since ancient times. Rock images, that preceded the written documents have reached us, and they inform us until nowadays for the evolution of humanity. The presentation and processing of information in graphic form, accompanies modern specialists and is an indispensable assistant for their work. The use of graphics software is an integral part of the skills, that modern engineers must possess. This paper proposes a new application of graphical representations in solving statics problems. The purpose of the proposed solution is to make the discipline of statics, which seriously hinders those who studying it, more clear and easy to perceive. A method for determining the moments of forces about a point, through the faces of rectangles is proposed. It is called the method of the rectangles. The summation of the faces on the individual rectangles is made in AutoCAD environment. This makes it possible to calculate the magnitude of any support reaction, by balancing its moment about an arbitrary point to the moment, about the same point of all other forces acting on the body.
