their estimates. Team E was the bestprepared, using an Excel file with laptop to input parameters and generate their estimates.Figure 5 shows the results for the second tank and teams “B” and “E” are in agreementwith the actual measurements. More time was allowed after the second test for teams toevaluate their predictions and to understand why their predictions were off.Figure 6 shows the results for the first tank with a non-negligible exit tube length. Thisconfused all of the teams. The teams applied Bernoulli’s equation to the entrance and notexit of the tube. Hence, the predicted drain times were longer than measured. Thestudents learn that heights are measured with respect to the pipe outlet and not inlet.Again, students were allowed a

Project AssignmentsA list of the projects assigned to students, as is from the class, is provided here below forinterested teachers to utilize or adapt to their teaching: 1- Using Brinell hardness indenter: a) Investigate the hardness of bobsled and skeleton runner material using lateral and longitudinal sections. b) Investigate edge effects on hardness. 2- For a piece of copper of bulk size, polish and etch it, and then investigate microhardness close to the center of the grains and progressively closer

. Lessons Learned and ConclusionsThere were quite a few lessons learned by the instructors from this PBL experiment:1) The hardest part about the experiment was, in the first place, picking a good PBL problem thatwas relevant to the class material at hand. Some of the criteria that the author used in selecting aproblem were: a) the design has to emphasize, or at least force the use of, concepts and equationslearned in the classroom, b) the possible solution designs should be relatively simple to make orbuild, not costly in dollar amount, and not very time consuming.2) The second thing learned was that the implementation of PBL takes a significant portion ofthe instructor’s time.3) The instructor needs to alert students to verify assumptions made in

that they do not initiate gross sliding, then only part of theinterface experiences slip leaving the rest of the interface in a locked mode. Similar to (3)partial slip can also be graphically represented by a conical surface (to be later referred toas a slip cone). Namely, at each increment i of the loading process we can build thefollowing cone: (Tx − Txi )2 + (T y − Tyi )2 − µ 2 (N − N i )2 = 0 (4)where (Txi , T yi , N i ) is an apex of the cone for this loading step. In general, there is aninfinite number of nested slip cones, all parallel to each other with the same angles N A B

To minimize the noise that is induced at the source subject B is in separate room. One approach to this case is to use the LMS algorithm to filter the data. Thisapproach can be found in part in B.

For example, when first goingthrough the derivation of the equation of motion for single degree of freedom systems, there is aninitial resistance to learning the material when all students see are box-spring examples. Instead ofstarting with the simplified model, a one-story building is presented to the class and the first step insolving the problem is the development of the analytical model for the system (see Appendix B).Once students are shown how a building can be modeled as a system of boxes and springs, studentinterest sharply increases.In order to be able to present civil engineering specific course content, some of the material is notcovered in the same depth as that in the mechanical engineering
