A comparison of flutterspeed obtained by using different number of modes (n=1,2…) of deformation will givesome indication of the degree of accuracy achieved. In this paper, two-degree of freedom(bending, pitch) are selected because they provides a system, which is not only easilyevaluated in physical terms but also from the computational point of view. Finally, thetwo-degree of freedom equations of motion can be derived using the Lagrange’s principleyielding to, ⎡ M hh b0 M hα b0 ⎤ ⎧ q&&h ⎫ ⎢M b

Label all of the materials for which the mer structures are shown in Table 4.3 of your textbook, and turn in the chart with your writeup. Based on your knowledge of how chemistry and structure of polymers influence strength, make the following direct comparisons and provide a reasonable explanation for why one is stronger than the other.

Boundary conditions are applied to the FEA model according to thespecification and experimental procedure. To simulate the locating and fixturing scheme duringwelding, the boundary conditions shown in Fig. 2 are imposed on the FEA model during thewelding steps. After the welding steps, the boundary conditions representing the fixturing areremoved to simulate the fixture release after welding.

skills necessary to succeed in engineering/technology education. A few have changed majors and some dropped out because of poor academicpreparations. Although this observation doesn’t help our enrollment, it is good from the students’perspectives in choosing their major and avoiding cost in time and money. Also, our observation hasprompted the mathematics department to evaluate their teaching of the algebra courses. The students, whowent from this course to the next level of ET courses, had a much higher rate of success than those wehad without this course in the past. This is indeed the most positive effect of ECET 1302. Also, it hasprovided the freshmen a pathway to explore engineering as a career choice.References1) J. B. Fraser, J. G

Good gradesin core classes are important for college admission but in today’s competitiveenvironment, the relative level of course difficulty also plays a significant role.Consequently, though class rank and GPA continue to be critical for assessing collegepotential, students are probably better off with a B in a College freshman English classthan an A in physical education in high school. Taking college courses while in highschool demonstrates to a college admission board the student’s capability, motivation,and that going to college is more than just his or her “Plan B.” Further, a college coursetaken while in high school can earn credits toward a college degree and simultaneouslyprepare the senior for the

In order to provide for an analog output signal, students shouldinterface an external D/A converter IC (DAC) to one of the parallel ports of the microcontroller.Students are required to develop a program to execute the tasks as follows: the analog inputsignal is to be sampled and converted to digital by means of an ATD module.
