For example, plate theory4 shows the maximumnormal stress, S, around a hole can be calculated using: qRo 2 F7 S t2Where q = applied pressure, Ro = outer radius, t = plate thickness and F7 is a stress factor basedon the geometry of the plate. In addition to hand calculations, the student responsible for the structural analysis(student “A”), is asked to defend the accuracy of his or her FE analysis. Students are encouragedto report structural error and explore submodeling techniques on the crown plate. For example,Figure 5 shows submodeling on the crown plate a student performed to validate the accuracy ofhis FE model

When looking at the overall numerical grades of the class (GPAs forthe course offering averaged for all students in the class), the summers again showed markedlyhigher average GPAs (Fig. 4). Finally, Table 2 shows the number of students that Q-droppedfrom the course as well as those who made a lower grade (Ds and Fs; both are actuallyconsidered failing grades within the department) – the data corresponds to the plot given in Fig.3 where summer offerings saw no q-drops or lower/failing grades.

theprojectile. Typically the comparator was set to switch at approximately 2.5 volts. The output ofthe analog comparator is open collector; this open collector output is connected to the +5voltsupply through a 10k ohm resistor. The output of the first analog comparator is used as a startsignal for the counter. The first sensor pair executes the start, and the second pair executes thestop. This start / stop is accomplished by the use of a J-K flip-flop. The start sensor wasconnected to the J input of the flip-flop and the stop sensor was connected to the K input. Whenthe start sensor was triggered high it sends the J input high and sets the flip-flop output 'Q' to alogic high. When the flip-flop's output is high the 1 MHz clock signal is then passed
