All componentsof the pneumatic system are standard products with no modifications.Figure 15 shows the floor location sensors used to signal the control measures when the cart is atthe desired floor. They are optical gate switches through which a metal tab on the elevator carpasses. Figure 16 shows the limit switches that are installed at the top and bottom of the mainrail on each side of the elevator support shaft. These limit switches are fed to the supervisorycontrol so it can automatically stop the motor drive in the event a user tries to move a car beyondsafe limits. Figure 15.

At theend of the sequence of the pictures we see that the heavy fluid has gathered to the left and thelighter fluid is positioned above the heavier fluid as expected.Figure 4 is showing a close up view of the instability. The wave length was determined to beapproximately  = 0.09 m and the corresponding wave number k = 0.07 m-1. In comparison,inviscid theory using equation (4) predicts that the Kelvin Helmholtz instability is amplified forall wave lengths smaller than  = 1.1 m. a) Horizontal position at t = 0 s. b

The subsequent lab explores 2nd order circuits anddemonstrates the significance of complex exponentials and the effect of dampening, whilereinforcing the notion of convolution. What before was a mathematical exercise in integrationbecomes an experience in probing a circuit with various input signals to see what happens. Norigor is lost, as they are still required to go through the drills of computing the convolutionintegral, but the process now has meaning. (a) (b) Figure 7 Measured and computed responses for an

the simplicity to be built by students over the course offive semesters. The research is designed to test two hypotheses: 1. A long-term design project that integrates knowledge from multiple courses strengthens student knowledge retention. 2. A large-scale design project requiring tools from many courses improves student problem-solving and design skills.By integrating five semesters of the mechanical engineering curriculum into a cohesive whole,this project has the potential to transform the way undergraduate education is delivered. Beforeand after testing is being conducted to assess: a) Change in retention between courses and b)Change in student problem-solving and design skills.The centerpiece of the hybrid powertrain is

The score on concept 8 (zero velocity does not imply zeroacceleration and conversely) for students in the Intervention #1 is statistically significantlyhigher than that for students in Control #1 (53% ± 3.9% versus 26% ± 6.0%, p<0.0001). Thisconcept measures a student’s understanding that: “An object can have (a) nonzero accelerationand zero velocity or (b) nonzero velocity and no acceleration.” Though the concept isn’t directlylinked to either of the i-Newton experiments for that specific term, the concept was covered inthe

This challenge led us to develop an engineering-wide research course which exposes studentsto the research process in a structured, step-by-step manner. The main difference between thiscourse and a more traditional approach is that the research topic is initiated by the student withthe assistance of the class instructors. The student then performs each step of the researchprocess using their chosen topic. Because the student will have an inherent interest in theproblem they choose to solve, we anticipate the student will be exposed to
