Naturally, there are advantages and disadvantages in using any of the abovemethods.Many engineers favor to employ the method using moment-area theorems because it has thebuilt-in advantage of graphical visualization during the drawing of diagrams of elastic weights(i.e., the bending moment divided by the flexural rigidity of the beam), as well as the drawing oftangential deviations associated with the deflected beams, in solving problems. There are twomoment-area theorems. Both of

Indeterminate Reactions and Deflections of Beams Using Model Formulas: A New ApproachAbstractThis paper is intended to share with educators and practitioners in mechanics a new approachthat employs a set of four model formulas in analyzing statically indeterminate reactions at sup-ports, as well as the slopes and deflections, of beams. The model formulas, in algebraic form, arederived using singularity functions. They are expressed in terms of (a) flexural rigidity of thebeam; (b) slopes and deflections, as well as shear forces and bending moments, at both ends ofthe beam; and (c) applied loads on the beam. The types of applied loads include: (i) concentratedforce and moment; (ii) uniformly distributed moment; and (iii) linearly varying

In addition to the technical courseobjectives, students will speak, write, and work in teams effectively, and communicateprofessionally upon completion of this course.

) illustrates the setting of our proposed Collaborative Project Based Learning (CPBL)model. Students are divided into groups to work on assigned projects in class, e.g. the design of aregister file in Computer Logic Design class (EE347), as shown in Figure 1(b). Usually, acollaborative effort is required to complete the project. Therefore, the students need to interactwith each other within the group. It has been shown that a high degree of interaction amongpeers can make students more engaged in the learning process. In addition, the instructor willinteract with every group to provide guidance in the design process, answer students’ questions,and address any observed problems.

The secondary needs are the actual need statements obtained bythe team after interacting with the different stakeholders. An importance rating is assigned toeach need based on a 1 to 5 scale in which each level has the following meaning:1. Feature is undesirable to most customers.2. Feature is not important.3. Feature would be nice to have, but is not necessary.4. Feature is highly desirable.5. Feature is critical.Finally, each need is classified according to the Kano Model of customer satisfaction as “Basic”(B), “Performance” (P), or “Exciting” (E).Although a total of forty eight needs were identified by the team, two aspects are evident

While these are still verybroad, some areas considered WMD by some would be excluded. An example of this is high-yield non-nuclear explosive weapons. In considering the course content and objectives, it was apparent that developing graduateswho were experts in all three major areas (N, C or B) was an unachievable goal in the time givento our master’s students (18 months to 2 years.)

Moreover, the comparison of these twotechniques provides an opportunity to explore a different pedagogy to this classic fluidmechanics experiment. In this work, the authors develop a model for predicting the pressure and temperature ofair charging into or discharging out of a tank. The model incorporates compressible flow in bothchoked and subsonic flow, and models the air as a general polytropic process of power n. Themodel is applied to two scenarios: (a) an initially pressurized tank discharged to atmosphere, and(b) an initially evacuated tank being charged from atmosphere.
