A one-dimensional, finite difference numerical heattransfer analysis of a 6” layer of concrete was performed to determine the benefit ofinsulating concrete with a top temperature of 100 ºF and a lower ground temperature of50 ºF. Insulation produces a 10 ºF higher temperature at the 2” depth where the waterpiping will be located compared to an un-insulated design; this was the reason for the useof insulation.A three-inch concrete layer was poured on the

Both examples begin with an undercut condition, which is detected automatically in theCamDesign program. Subsequently, appropriate changes are suggested by the program that areused to resolve the undercut design.Example 1 - The first example involves a flat face translating follower. The design requirementsin terms of geometrical and kinematic properties of the cam and follower mechanism are shownin Table 1. Fig. 2(a) shows the resulting cam profile, and Fig. 2(b) is the warning messagegenerated by the program that reports the undercutting problem and provides a solution forresolving the undercut design.Table 1 – Design

While the instructor must still grade each laboratory report, his/her feedback isreinforced and complemented by the peer feedback and evaluation.We will continue to use this approach to peer evaluation of laboratory reports in the coming year,and will add the use of a newly developed rubric to assess student success in outcome b, listedabove. Additional data will allow us to observe whether the apparent trend of increased gradescontinues. We will also consider further modifications to this approach, such as the addition ofan oral reporting component as suggested by one of the

The instructor then works through the exercise by interacting with the class,the final result being the continuity equation in Cartesian coordinates.Comments: This exercise engages students and allows them to take ownership of the continuityequation.
