Many of these problemswere adopted in our class either as examples or as homework problems. Our purpose isnot simply to solve these mechanics problems, but to teach explicitly the process ofmodeling, formulating and solving a real problem. For example, the two problems in Fig.1(a) [2] and (b) are

examples thatfollow will illustrate the use of CAD-based graphical problem solution to faculty unfamiliar withCAD software to encourage CAD-based graphical analysis in student assignments as well asspark interest in its use for themselves.The first rudimentary example of using graphical analysis with CAD as the solution methodrepresents a typical problem found in Engineering Statics. This force analysis problem requiresfinding the tension in two cables supporting a 200 pound weight. One cable (A) is 45° from thehorizontal upward toward the left while the other (cable B) is 15° from the horizontal upwardtoward the right. From a Free Body Diagram (FBD) shown on the left side of Figure 1, we seethat we know the magnitude and direction of the weight

Using a Sub-function: Students are provided with a function which will generate a pseudo-square wave time series given the frequency, amplitude, duration and sampling frequency. Theyare expected to modify their previous song script to utilize this function. This exercise givesthem experience at calling a subfunction and shows the usefulness of sub-function. A copy ofthis function is shown in Appendix B. This challenge illustrates both writing a function andutilizing a sub-function.3. Wav File Distorter: Students create a function which could read in a

Those learning objectives were based onBloom’s Taxonomy levels of learning and on Krathwohl and Bloom’s degree ofinternalization. The course was intended to address five ABET technical outcomes (3.a, 3.b,3.c, 3.e, and 3.k) and three non technical or soft outcomes (3.d, 3.g, and 3.i). The courseassessment matrix was used to map the course learning objectives into those outcomes andindicate whether each objective addresses the corresponding outcome marginally,moderately, or substantially. It was demonstrated that ABET requirements were satisfied inthis course.Assessment of active learning outcomes in that one section was

ObjectiveThe primary objective of this study is to research ways of improving the education of AfricanAmericans by significantly increasing the number of college graduates from Historically BlackCollege and Universities (HBCUs) using object-oriented software analysis and designmethodologies. HBCUs are institutions of higher learning, whose principal mission is to educateAfrican Americans. Based upon this objective, there are two significant questions to beaddressed by this research: a) Is it possible, through innovative measures, for the current set of HBCUs throughout the United States to educate African Americans on a massive scale? b) What is the best way to design the format and presentation of

explanation of an uncertainly formula derivation.RLC circuit with hysteresis lossA series RLC circuit can be set up with a sinusoidal source. A dual trace scope is used to analyzethe circuit. The scope usually has coaxial inputs so one side is always grounded. The voltageacross (L + C) and C can be measured and data is entered into Excel. Sinusoidal datamanipulation is easily implemented in Excel so the voltage across any two elements can begenerated in Excel. Lissajous figures can also be generated by Excel. Lissajous figures are afamily of curves described by the parametric equations x(t )= A cos (at-b) and y(t) = B cos (ct-d).The figures generated by Excel can be compared to the scope data in x-y mode as well as thecalculated data using the
