One goodapproach to achieve this purpose would be to examine alternative materials available for makingthe product and choosing the best material based on the product service requirements.

By letting the free body of a system undergo a strategically chosen compatiblevirtual displacement in the virtual work method, we can solve for one specified unknown at atime in many complex as well as simple problems in mechanics without having to solve coupledsimultaneous equations. The virtual work method may initially appear as a magic black box tostudents, but it generally kindles great curiosity and interest in students of statics. This paper pro-poses an approach consisting of three major steps and one guiding strategy for implementing thevirtual work method.

At Penn State Erie, The Behrend College,we offer first-year Mechanical Engineering Technology (MET) students the introductorymanufacturing materials and processes course. The course has both a lecture and laboratorysegment. During the lab segment of the course, students have the opportunity to experience:material testing, plant tours, manufacturing processes, statistical process control, andinspection/measurement techniques.With 10 PIM machines, 3 extrusion lines, 2 thermoforming machines, and 2 blow moldingmachines, Penn State Behrend has the largest educational plastic injection molding (PIM

The authors examinepossible improvements to the method used and suggest other possible applications for thetechnique developed. The animation is used in strength of material classes for the purpose ofanalyzing mechanical failures of components subjected to severe tensile loading conditions.

Each new technical innovation has requireddiscoveries in materials to surmount barriers and limitations. This leads to an overlap betweenmaterials science and almost every other engineering field. Electrical engineers use materialsscience and engineering to produce computer chips, lasers, and superconductors. Structuralmaterials such as concretes for roads and metals for buildings and bridges are crucial to civilengineers. Mechanical engineers must consider the strength and long term reliability of thematerials used in their designs. Light weight, strong materials are
