increase the useful life and residual valueof each aircraft. Boeing is so convinced of reduced maintenance requirements due to thecomposites structure that they are issuing long term maintenance agreements with the aircraft, apractice normally unheard of in the industry. Boeing also believes that due to compositematerials’ resistance to condensation, it would allow engineers to increase cabin humidity toenhance passenger comfort. The 787 will also enjoy a 30,000 to 40,000 pound reduction inweight compared to its closest counterpart, the Airbus A330-200. Composites continue toreplace aluminum as the material of choice, and as a result, aluminum comprises only 12% of the787 airframe structure. In the future, Boeing estimates a 19:1 part count

To supplement the lecture material, handouts contained pictures, graphs, andtables that could not be replicated well on the chalkboard. Some handouts were mini-lessons thatcovered additional material not in the lecture or textbook,1 such as the impact test data in Figure1. In addition, homework assignments were listed on separate handouts as shown in Figure 2. Page 11.1193.2MET 180, Class #7 MET 180Charpy impact testing of the Titanic’s hull

An added benefit was an increased use of thefoundry and interaction between the programs.IntroductionMotivations for developing alternative resources fall into two categories. First, there is neverenough money to satisfy typical requests for support. Second, there may be resources next doorthat can be used with improved awareness and cooperation.

This allows removal of the copper power distribution “backbone”, leavingminimal amounts of copper behind. This is a problem in mechanical and materialsengineering. The opposing design requirement is that the connections do not break underthe usual wear, tear, usage of an automobile in all of its sometimes challenging thermaland vibration environments. The pre-determined break away feature

. Approximately 210students take the course each year. The course is broken into three sections – structure ofmaterials, mechanical properties of materials, and microstructure of materials – with about 75%of the lecture time devoted to metallic materials and about 15% devoted to plastics and ceramics.The remaining 10% is allocated for three in-class tests. A typical course/lab breakdown is givenin Table 1. There is no follow-on course, and Materials Science is not a pre-requisite for anyother ME department courses. With limited time for in-class instruction and a student populationthat saw Materials Science as a terminal course, something needed to be done to make thestudents participate more actively in their learning and to give clear value to the

seed was planted in 1959 by Richard Feynman when he postulated that it was possible to write“the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin.” 1 The idea laydormant until the early 1980s, when technology made it practical to visualize and evenmanipulate individual atoms on surfaces. The result was a new realm of science andtechnology—the nano-realm. The nanoscale is between the microscale and the atomic scale.With respect to lengths, the nanoscale ranges between about 1 and 100 nanometers; it mayextend into the hundreds of nanometers.Being able to understand and manipulate objects and functions at this scale has extraordinarypotential for two general reasons. The first may be obvious. Feynman’s proposal is an

We are certain that many of these activities are not unique to our curriculum, and weacknowledge inspiration from others using similar hands-on
