reasons for selecting a pump test and PTC 8.2 for this exercise. Perhaps themost obvious is that there is a pump available and it had been used in the course many timesbefore! Another is that space constraints in the laboratory usually require that the pump testingset-up be disassembled after use in a given Spring semester so that it must be (can be)reassembled by the students for “their” pump test. Besides these, there are also reasons thatderive from PTC 8.2 itself. Unlike many other PTCs, PTC 8.2 provides for two levels of testing;a “Type A” test and a “Type B” test. Type A testing is similar to most other PTC tests; it isintended to be run on large equipment (in this case, a boiler feed pump) in the as-installedcondition and it requires

As a Thermal Ad- visory Engineer for IBM’s Systems & Technology Group from 2011 to 2013 he designed and developed electronics thermal management solutions from the die level up to full server systems. Dr. Moore joined the mechanical engineering faculty at Louisiana Tech in September of 2013. He holds a joint appointment with the Institute for Micromanufacturing (IfM) where he works on advanced materials and devices for energy applications with an emphasis on nanoscale thermal energy transport.

TAs arerecommended by the teaching faculty in the related subject areas, and those chosen all havepreviously completed the course with an earned grade of B+ and above.The paper presents our findings in running the faculty driven peer FSGs for Statics andThermodynamics. Of all eligible students who registered for these courses, more than 20% of thestudents participated in the FSGs. Post

Before breaking theassembly into the individual groups, the facilitator reviews the rules for the C-Sketchingsessions, which will be identical for both sessions and are: (1) criticism is not allowed, (2) “wildideas” are welcomed, (3) build off each others’ ideas; similar rules to Osborn’s brainstorming[40,39].

mechanical engineering program outcomes – what students are expected to know andbe able to do by the time of graduation. Old criteria simply required students to complete coursesin specific areas, new criteria requires departments to identify specific outcomes related to theprogram. It was critical at this step to identify outcomes that could be both measurable andassessable. After much discussion, faculty chose to approve the outcomes identified by ABET asa-k and mechanical engineering outcomes l-o.ABET Outcomes Our Mechanical Engineering graduates will have: (a) An ability to apply knowledge of mathematics, science, and engineering (b) An ability to design and conduct experiments, as well as to analyze and interpret data (c) An ability to design a

In general, none of theattempts seemed to be comprehensive- each targeted certain concepts and/or principles.

After they collected the necessary geometric data, they were tomake a sketch of the system and determine the Instantaneous Center of Rotation (ICR). Thelaboratory assignment gives the students the velocity of point B at an instant in time and thestudents were then asked to find the velocity at point C using the ICR. The purpose of thislaboratory was to present a real-world system that uses some theoretical concepts such asdetermining an Instantaneous Center of Rotation, Rigid Body Motion, Relative VelocityCalculation and Angular Velocity Calculation. The students seemed to enjoy this laboratory andworked very well in their groups to determine the solutions to the questions

The ease of use of such packages combined with the ever more‘impressive’ post processing capabilities have seen a trend whereby engineers,particularly more junior engineers believe these packages can be used in isolation andtheir predictions believed in with absolute confidence. This paper re-emphasizes the importance that pre-analysis analysis or ‘guesstimation’must be given if catastrophic mistakes are to be avoided and the engineer is to retain a‘feel’ for the physical factors at
