of proven methods and artifacts.The operations that must be addressed in order to realize a design repository are 1) arepresentation for a design knowledge element, 2) a method for storing or uploading theknowledge, and 3) a method of searching and retrieving the knowledge for reuse. Severalimplemented repositories provided the background for the structure of the design knowledgerepository. Szykman and Sriram1 developed a design repository software system that providedinsights into the use of design repositories in conceptual design. Bohm et al.2 developed a datarepresentation for use in design repositories that captures multiple attributes of components orassemblies including core elements of form and function.

) roadconditions by overcoming various obstacles. A 6 wheel drive off -road vehicle‟s performancemay be improved by controlling individual wheel torques [1]. Individual control of wheeltorques such as traction control and anti-lock braking improve vehicle handling and stability incornering. Multidisciplinary Design Optimisation (MDO) is a very useful technique for solvingany multi-body dynamics problem [20]. MDO is a body of methods and techniques forperforming the optimization so as to balance the design considerations at the system and detaillevels. Another approach to improving vehicle performance is to integrate both the vehicleoperational properties and adaptive vehicle dynamics [2, 3, 4]. However, analysis of mass andgeometric parameters may provide

absorbing materials. A performancecomparison of the vibration isolation system between a gas and an electric engine was alsostudied. A graduate and an undergraduate student performed the experimentation and datagathering, and with the aid of their instructor, analyzed the nature of the vibration. An effectivesolution was implemented that allowed the TASE gimbal to function satisfactorily and theairplane to achieve mission goals.1. IntroductionLaser targeting systems implemented on Unmanned Aerial Vehicles (UAV) such as the TASEgimbal depends on the accuracy of instruments such as accelerometers, gyroscopes, pressuresensors, and Global Positioning System (GPS) to determine accurately the position and distanceto target. These instruments almost

up. These craft may be designed in response to a set missionstatement (e.g., in response to the yearly AIAA design competition) or according to the interestsand objectives of the student teams and instructors. In the Detail Design courses, each teamselects one (1) component or set of subsystems from their craft—a wing section, a tail section, asatellite tracking system—and creates scaled models that they then subject to various tests, suchas wind tunnel, vibration, and static structural tests. These test results are then compared tocomputer-based simulations and are presented by each team at a formal briefing at the end of thesemester. This formal briefing is open to the university and is scored by a panel consisting offaculty members and

308Each team is to build two bridges made solely from spaghetti and epoxy. The objective is toconstruct a design that will carry the heaviest load while meeting the specifications summarizedon the following page. Completed bridges are loaded until failure.Rules and Specifications:1. The bridge is to be built solely from spaghetti and five minute epoxy. Per three or four person team, the two bridges are to be as identical as possible with the ONLY exception being that one bridge can have epoxy at any location and the other bridge can only have epoxy up to 1.5 cm in any direction from the node. Disqualification will result if this is violated.2. The bridge shall be free-standing and must span two level surfaces which

Fastener types, such as variousrivets, bolts, and welds are discussed, alongwith typical failure modes (fastener shear,bearing, shear-out, bolt bending, pull-through,etc.), edge distance influence, improperlyinstalled fasteners, and weld efficiency. Twolaboratory sessions are required formanufacturing and testing fasteners. Studentsmanufacture a number of specimens forsubsequent testing (Figure 1). Strips of metalor composite material are fastened with variousrivets and bolts for axial tension or fatigue Figure 1. Students constructing fastenertesting.

In order to educateengineers who are capable of applying their fundamental understandings of science to diversesocietal problems, educators need to be aware of the importance of this level of students’knowledge, and the role it plays in learning.Bibliography1.

. In addition to significantlyreducing the cost of offering an experimental component, the experimental module provided anopportunity to demonstrate a modern approach towards control systems based on computers(digital control).II. Experimental setup descriptionThe setup consists of a small DC electric motor driven by a 5 V pulse-width modulated (PWM)signal. The motor is attached to the free end of a light carbon rod, while the other end of the rodis connected to the shaft of a low-friction potentiometer. The potentiometer is fixed on a plasticstand at the proper height, so that the pendulum can swing freely (see Fig. 1).

’ perceptions of engineering activities.As engineering design activities are predominant in most K-12 curricular and professionaldevelopment programs,1 understanding students’ motivation in engineering design activities iscritical. Is the motivation to learn science and mathematics the main reason for the shortage, orare there other factors such as insufficient analytical skills that demotivate students inengineering design activities? Although there may be numerous factors that contribute to the lackof motivation to study engineering, understanding the connection between students’ goalsorientation and their confidence in their abilities to perform should positively contribute toknowledge building in the field of engineering and technology education

This research supports the common belief held by many faculty: studentgrades are not the best indicator of student quality.IntroductionCritical thinking is the process of gathering information and actively analyzing, synthesizing,applying, or evaluating it in order to make decisions, form beliefs, or choose a course of action 1.Increasing engineering students‟ critical thinking skills is important because the higher theircritical thinking level, the more successful they will be in solving problems. Students must thinkcritically in order to gather data to solve problems, defend their solutions to problems, makeopen minded decisions, and communicate their ideas.Critical thinking is typically measured in terms of skills associated with
