Abstract

This notebook presents idealized approximations of forces in a rigid system, which consists of a variable-mass beam supported at its ends ( points F1 and F2, designated by filled up-triangles ) and a variable-mass object that is borne by the beam.  The massive object is designated by a filled down-triangle, and its location on the beam ( center of gravity ) can be moved along the beam's length.  The adjacent bar chart and numeric reports indicate the status of the system's forces ( arbitrary units ) as a function of the mass and location on the beam of the object, and the mass of the beam.  More complicated rigid systems also will be presented using the aforementioned format.
