compatible with what is required in the virtual work method but is notcommonly recognized and emphasized. The virtual work method is initially not easy to learn formany people. It is surmountable when one understands the following: (a) the proper steps andstrategy in the method, (b) the displacement center, (c) some basic geometry, and (d ) the radianmeasure formula to compute virtual displacements. For learning and pedagogical purposes, thispaper includes seven examples with various levels of challenge.I. IntroductionMore often than not, it is manifested that the virtual work method is used to treat problems in-volving mainly machines. This manifestation comes about as a consequence of focusing on thedetermination of the equilibrium configuration
course and at least knew Lagrangian equations.All students in these two groups had little or no background in applied multibody dynamics andno experience with virtual prototyping software.Based on the technical background of the students, the approach of combining theory with theuse of software was utilized to deliver the AMD course. Such an approach has several benefits.One obvious benefit is that students are usually attracted by the use of simulation tools. After theinstructional approach was determined, other teaching materials were chosen as follows:(1) Textbook and reference books a) Thomas R. Kane/David A. Levinson, Dynamics Online: Theory and Implementation with Autolev, Online Dynamics, Inc., 2000 b) Ahmed A. Shabana

, students might gradually formsimple impression of beam as what we draw on the paper and cannot realize or identify Page 11.839.3that ski boards under a skier’s feet are also beams, a person standing on a ladder is abeam problem etc. Some MoM textbooks, such as the one by Hibbeler, [3] have manyexamples presented in the way as they are in the real world. 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

method of incorporating animation into the student experience in the analysis of dynamics(especially vibrations) problems is presented. After a student models the problem, draws free-body diagrams, and derives equations of motion, he/she then obtains the solution for the positioncoordinates as functions of time. The student generates and plots the solution within a simpleMATLAB program in which all parameters, such as mass, stiffness, damping, lengths, initialconditions, etc. can be easily changed. The solution can be generated using either a closed formsolution or a numerical differential equation solver. In either case, at the end of the program, thestudent can animate his/her own solution by running an animation function file provided by

because they have the final result. Changing the inputs and monitoring theirinfluence on the output will definitely help inspire students desire to answer the “what if”question, hence helping them to think out of the box and become a better designers who look atthe problem from all perspectives analyzing all possible scenarios. The impact of using this toolwill be monitored through regular surveys among the students, and through statistical analysis ofstudent’s performance.References1 R. C. Garcia and B. S.
