Teaching Deflections of Beams: Advantages of Method of Model Formulas versus Method of Integration

Le résumé fourni par la source

The method of model formulas is a new method for solving statically indeterminate reactions and deflections of elastic beams.Since its publication in a recent issue of the IJEE, 1 many instructors of Mechanics of Materials have considerable interest in knowing an effective way for teaching this method to enrich students' study and their set of skills in determining beam reactions and deflections.Moreover, people are interested in seeing demonstrations showing any advantage of this method over the traditional methods.This paper is aimed at (a) providing comparisons of this new method versus the traditional method of integration via several head-to-head contrasting solutions of same problems, and (b) proposing a set of steps for use to effectively introduce and teach this new method to students.It is a considered opinion that the method of model formulas be taught to students after having taught them one or more of the traditional methods.
