problems themselves is typically not much different from writing a standardexam. Even when superheroes are involved, I try to keep dimensions, weights, forces withinrealistic parameters. To reduce development time, I have been able to repurpose some drawingsfor subsequent exams (eg. the Statics & Dynamics exam in Appendix B was re-written as aphysics exam in Fall 2017), and I use the same final exams each semester. Samples of pastexams are available in Appendices B-E.When selecting a theme, there are several potential approaches. The calendar can suggeststorylines – such as an imaginative costumed child in late October or movies like How theGrinch Stole Christmas in December. Alternatively, movies targeted to families that involveaction or

engineering program is that students canconduct mechanical system designs including mechanical component design. To design beam-like components such as beams and shafts, we must analyze the loading conditions on thecomponents, that is, the Shear force and Bending moment diagrams (the S/B diagrams). So, theability to draw the S/B diagrams on beam-like components is an important skill for mechanicalengineering students. In our mechanical engineering program, the S/B diagrams of a beam wereintroduced during Engineering Statics by using the method of sections in the first semester oftheir sophomore year. In the second semester of their sophomore year in the course Mechanicsof Materials, the S/B diagrams were discussed again by using both the method of

dynamic systems governed by second-order ordinary differential equations exhibit a “natural frequency” or does the term apply onlyfor undamped and underdamped systems that experience oscillatory behavior? Does it makesense that a mathematical definition of natural frequency exists without knowing if the systemwill oscillate? Can expressions for undamped natural frequency include dissipative terms? Thispaper presents a series of example problems in which these questions arise.Models and BehaviorMass-Spring-Damper Second-Order System Consider the classical lumped-parameter linear model of a mass-spring-damper system,depicted in Figure 1, with mass m, viscous damping b, linear stiffness k, and applied force F(t).

The sample size was quite small in this study, so there may be benefit in repeatingthis study with a larger number of students, but based on the lack of obvious improvements onthe common exam problems, we do not recommend implementing the reordered syllabus withoutadditional study.References:[1] Hibbeler, R.C., Engineering Mechanics: Dynamics, 14th Edition, Prentice-Hall, Inc., 2015.[2] Boresi, A.P., R.J.

specific data collectiontools. Two threats to the validity of the data collected by using the think aloud method are; (a)incompleteness due to synchronization problems and (b) invalidity due to problems with workingmemory. Thinking aloud takes place concurrently with the cognitive process, hence a cognitiveprocess takes longer when think aloud method is used. For example, subjects frequently reportthat sometimes verbalization does not keep up with the cognitive process and that their thoughtprocesses may look incomplete or contains “holes” of which it is necessary to assume that anintermediate thought occurred here. The second reason states that “if the task is non-verbal andcomplicated, then verbalization will not only cost time but also space in

In thisexample, students in MC364 used a SOLIDWORKS model (Figure 4(a)) to discover theprinciple of superposition for stresses due to combined loading. To assist in student visualizationof the problem, students were provided with a 3D printed offset link (Figure 4(b)) that wasprinted using the SOLIDWORKS model. In addition to enhancing student engagement, thisprovided an opportunity to briefly discuss current 3D printing technology.

After determining the frequencies and mode shapes, estimate the locations of modal antinodes and place the shaker at those locations and force at the corresponding natural frequency to induce resonance. Ensure you have discovered a resonant frequency by adjusting the frequency of vibration to identify a maximum response acceleration. Measure the mode shape using the iPods. 3.
