b: characteristic length a: speed of sound Mach Number Ma = V / a V: speed of airplaneAn efficient wing has a large lift-to-drag ratio CL / CD. The lift force Lf of an airfoil can be alteredby changing the angle of attack α. This actually represents a change in the shape of the object, andthese shape changes can be used to alter the lift when desired. Various types of airfoils have beendeveloped over the years in response to changes in flight requirements. Typical shapes of airfoildesigns are sketched in Table 2 and the corresponding experimental lift coefficients CL
boundaries between engineering and technology, it became clear that engineers were not adequately prepared in laboratory techniques. ‚ By late 1990s ABET EC2000 appeared, requiring institutions to develop mission and objectives for each program, to develop outcomes that could be periodically assessed, and to continuously improve programs’ offerings.The new EC2000, referred to engineering laboratories as a significant part of engineeringeducation in 4 places; Design of experiment (3b), Use of modern tools (3k), Facilities (newcriterion 7), and Support (new criterion 8). Outcome 3.b, in particular, states that engineeringprograms must demonstrate that their students attain: an ability to design and conductexperiments, as

These students had enough resources to do relatively Page 24.1222.16well in the class (B range) and did not seek out additional time on the devices. However,the student engagement was much different for the students who had traditionallystruggled with the class or dropped out near the end of the term. The struggling studentschecked out individual iPods at a rate as high as the top students and actively participatedin the collaborative experiences. In other words, this group of students became engagedin their own learning and their success rates improved. These students did not give up ondifficult design

Asdescribed on the nanoHUB.org website, key characteristics of the nanoHUB.org simulation toolsthat make them good resources for incorporation into classroom environments are: a) they wereproduced by researchers in the NCN focus areas, b) they are easily accessed online from a webbrowser powered by a highly sophisticated architecture that taps into national grid resources, andc) they provide a consistent interactive graphical user interface—i.e. Rappture, which makeseven the most esoteric computational model approachable to experts and non-experts. Rapptureis a toolkit that allows the incorporation of a friendly graphical user interface with the simulationtools in the nanoHUB.org (McLennan, 2005) 2 . For example, Figure 1 illustrates a typical

These notches were not symmetrically situated around the offset notch due tosome loading frame fixture limitations.2.
