List any other topics or concepts in fundamental mechanics (Statics, Dynamics, Mechanics of Materials) where students consistently have difficulty. List any topics of concepts that you find students have difficulty integrating or transferring into other contexts (i.e. when they do not have a “textbook” problem or when they have to use the concept in a different course). Could you suggest some specific problems that include these concepts? Page 8.1302.3 Any other comments?Proceedings

Laboratory sessions provide examples that students can see, feel and hear, andprovide an alternate mode of learning to those for whom reading the textbook or hearing lectureis insufficient.

Figure 2: Example cross-sections to satisfy the design objectives. In the diagrams shown, the layers are fastened together at discrete locations using bolts. Adhesives may also be used to fasten the layers together.In addition to the geometric combinations, the layers are also made available in multiple materials.The author has used two different strategies regarding available materials during the past twoyears of teaching Engineering Mechanics. The first strategy is to provide the students withreusable layers made of aluminum, steel, and brass. The layers are prefabricated with holes atdiscrete locations along their lengths. The students simply “stack” their design and fasten thelayers together tightly using bolted connections

Lecture notes (createdusing Microsoft PowerPoint) are made available to students online. Streaming video lectures(created using SmartBoard technology and video editing software) allow students to accesslecture material and examples at any time. These asynchronous instructional tools allow thematerial to be covered in a number of different ways, appealing to diverse learning styles, so thatthe material may be covered more comprehensively using less class time than in a traditionallecture format. These instructional tools will ultimately be placed in the context of larger instructionalmodules in mechanics

Whenannealed the net surface area is reduced as these surfaces add energy to the material. Therefore itis vital that students understand surface energy so that they can understand the effect whichstructure has on properties and that which processing has on structure. Students combine severalof the lattices built earlier and measure surface energy through the “broken bond” model. Thebroken bond model is then used to explain why dislocations are also unstable and eliminatedduring annealing.Amorphous MaterialsIn order to understand the behavior of non-crystalline solids it is important to understand

teaching of materials today is still coloured by its more recent history, in which thephysicist and chemist played a great part. The starting point (taking the physicist’s view) isSchroedinger’s equation; the reasoning leads on to concepts of atomic bonding, to thegeometry of molecular and crystal structures, to crystal defects and the glassy state, to alloytheory and phase stability, the kinetics of phase transformations, the mechanisms of plasticityand fracture … and so on, gradually moving up through the length-scales from the atomisticthrough the microscopic to the macroscopic. This understanding is the foundation on whichthe subject rests, and for that reason there is a reluctance to approach it in other ways. But itis a path that creates a

We are developing WWW-based tutorials that provide step-by-step instructions onsetting up and running the simulations discussed above.
