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

The second sample question examined understanding the principles of light sensor operationand, from physics, how light intensity from a point source falls off as a function of distance.This behavior of light is important because most fire-fighting robots depend on light sensors todetect a flame, and many use reflectance sensors to determine distance to arena walls and otherobstacles.Q2: The light intensity from the source O measured in points A and B equalsIA = 4 W/m2, IB = 9 W/m2.

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.

Besides addressing the mathematical background issue,these programs also address help-seeking strategies such as how one prepares for a test,seeking assistance from faculty, peers, and other available resources to study andcompleting assignments. 11Purpose of the StudyDue to poor performance in calculus among freshman students in the last ten years, theundergraduate calculus course has attracted an unprecedented level of national interest. 12Many of the freshman engineering students fail to meet the minimum grade criterion ofA, B, or C in their calculus course. 2 Thus, researchers have conducted

The main one is theindustry shift to use Programmable Logic Controllers (PLCs) rather than custom analog circuitsfor low-number applications. This is primarily due to: a) increase in labor costs b) decrease in PLC cost c) decrease in number of personnel capable of working with electronic analog circuits d) added flexibility that results from control implementations that depend on software rather than hardware e) increased level of reproducibility that results

In assigning final lettergrades, the instructor rank ordered all students and examined the distribution for gaps betweenpopulations to differentiate students earning an “A” from those earning a “B”. The resultingdistribution of grades is shown in Figure 2. It is see that from 2003 to 2005, there is a clear meanshift from “F”s to “A”s, even though the course grading was not relaxed. Indeed, the course wasgraded more strictly. The cut-off between “D” and “F” was set to a lenient 20% in 2003 and a Page 11.879.6slightly more stringent 25% in 2005. Similarly, the cut
