The conversion factors for SI system are:
And for the English system are:
In this module, the forces (elements Force, Friction and Resultant) are applied to elements object (elements Point, elements of beam or elements of solid), placing these at adjacent cells to the objects. Each element object, if isn’t placed at the chalkboard’s border, has 8 adjacent cells. This module have 27 elements, presented below. With a description of each one, its data and its number of equations. Notice that some elements add two or three equations, depending on the forces applied to it. If all forces are horizontals, or verticals, two equations are added, otherwise three equations are added.
