Session 3538 3D CAD Approach for Vector Graphics Daniel M. Chen Central Michigan UniversityI. IntroductionThe purpose of this study was to investigate the effectiveness of the 3D CAD approach in theanalysis of concurrent coplanar and non-coplanar vector systems. Much engineering data isgraphical in nature. Graphical methods utilizing such data can provide comparable accuracy foranalysis of vectors, such as forces, velocities and accelerations, in mechanics, machine designand structural analysis 1.

researchconducted by the Engineering Media Lab at the University of Oklahoma in applying Java andVRML (Virtual Reality Modeling Language)1 for performing engineering design and analysis onthe Internet.To demonstrate the potential of using VRML and Java for design and analysis over the Internetan L-shaped beam subjected to a point load along any or a combination of three directions i.e. X,Y and Z is chosen. The user can vary the length and height of the beam. For the sake ofapplication simplicity the cross-section of the beam is constant. The user can choose the materialproperties of the beam and the loads to which the beam is subjected. After the user submits thevalues, the Java program generates the new L-beam, meshes the beam automatically andcomputes

To this end,the Keirsey instrument was used [Keirsey 1984,1999]). As with the 6-Hats TFS, the MBTI typeswere used in accordance with a simple algorithm to form MBTI based design teams. Thisalgorithm is based on the MBTI TFS goals as seen in Table 1 below. Details of this process aregiven below in Section III: MBTI Based Team Formation.

In a reverberating container4, (Fig. 1), solid particles are moved towards the nodes of the sound field7. Bydriving different natural frequencies, we can generate nodal planes of various shapes.

The space consists of nine teaming areaswith movable partitions between some of the areas. This allows groups of up to 30 in two of theareas and up to 60 in the center area. There is space for 28 teaching assistants grouped in 6villages each with their own lockable storage space and work surface. Space was also added for acomputer with a scanner, color printer, and laser printer. This gave students a space that could beused to create reports, presentations, or anything requiring that type of technology.

The shift from the lecture-based, passive-learning model to a learning-centered system of learning does notjust happen. It requires a purposeful faculty development project that challenges instructors to commit to positivechange. Such change in the classroom creates active involvement, student interaction, and intellectual engagement.Additionally, implementing new pedagogy will empower students to become actively involved in the class.

Others, however, are time-dependentanalyzers. The gas chromatograph is an example of a semi-continuous analyzer where columnelution time of less than one to ten minutes is required before a recorded peak is complete.A paper-tape monitor for hydrogen sulfide is another example of a semi-continuous analyzer.

The Beam Data VI determines the harmonic nature of the beam, and the FrequencyData VI drives the beam specified frequencies, and at each frequency, determines thedisplacement at the end of the beam based on acquired data and harmonic data.Theory A shaker is driven, with displacement y, to displace the fixed end of a cantilever beam andimpart harmonic motion in the beam. Mounting two strain gages on the beam as shown inFigure 1 allows the measurement of maximum strain in the beam as the end of the beamoscillates in x direction.
