In the first Machine Design course, junior mechanical engineering, the students learn tocalculate the bolt/rivet and joint members stresses. Due to the time constraints of a firstMechanics of Materials course there is generally insufficient time to verify the assumptionsmade in developing the theories with experimental verification. Experimental validation allowsthe student to delve into the corresponding approximate nature of these theories.The Stress Analysis Laboratory practice improves the students’ comprehension of the stresstheory learned in lecture.

rigorous use of vectors and calculus. Theapproach taken is typically applicable to all problems in two and three dimensions. Thisapproach is preferred over planar scalar approaches because it is applicable to a broader range ofproblems. With these methods students eventually develop their own scalar short cuts; however,they have a complete understanding of the limitations of the methods that they employ.The first courses in mechanics are the foundation of a students understanding of mechanics. It isessential that engineering students not only come away from these courses with a thoroughunderstanding of the theory, but also with a physical insight into engineering mechanics. Forthis reason laboratory experiences are integral to these first two

. Microhardness testing can be used to measure these profiles and work out the diffusivity of oxygen in titanium. A laboratory experiment has been developed in which commercially pure titanium is annealed in air, the microhardness profiles are obtained, and the results are analyzed to obtain the activation energy for diffusion. The value obtained was close to that for tracer self- diffusion in α-Ti. This inexpensive experiment, based on scientific literature from the 1950s, gives the students hands-on experience with the experimental methods and interpretation of the data used to study this very basic materials behavior.IntroductionTitanium is well known for its excellent resistance to corrosion primarily due to

The teachers conducted research on the use of fiber reinforced composite materials tostrengthen and stiffen the components of bridges. For the past two decades, composites havebeen introduced to the construction industry as a practical way to improve the load carryingcapacity of existing concrete, steel and wooden structures. Wood was chosen for the RETresearch due to the availability of wood beams, the limited duration of their summer researchexperience, and the ease in creating easily transportable in-class laboratory modules.Specifically, the teachers investigated the factors affecting the strength of the bond
