advisorbut they are encouraged and free to seek help from all faculty in the school.To quantify whether CAD/CAE is being used intelligently we asked University of GuephProfessor Emeritus Jan Jofriet to review four capstone design reports (which incorporated CAEas part of the design process) against a number of ‘intelligent use’ indicators. Professor Jofriethas an extensive background in researching and teaching of FEA. The projects utilized eitherCFD or solid mechanics within their design. Six measures were used to assess the level ofintelligent CAE use. Table 1 provides the six measures and the descriptors used for each of thesemeasures.Observations and DiscussionOne of the most valuable outcomes that has resulted from this effort in the second

educational programs (for instance,Electrical Engineering) do not have a background in robot manipulators. Hence, they arenot expected to have a background knowledge of kinematics which is a prelude to thestudy of human leg modeling and control. Hence, the first section of the educationmodule is to teach students the concept of kinematics using interactive tools andgraphical animations. Students who have used this section of the educational modulehave found it to be a ‘fun’ tool and have been able to assimilate the concept of kinematicsexceptionally well even though they have not been exposed to the study of kinematicsprior to their experience with the interactive module.After having understood the topic of forward and inverse kinematics and with

As part of a collaborative, large-scale NationalScience Foundation project, this paper describes our first efforts to develop MEAs whichincorporate a laboratory or hands-on component.We will explain more about MEAs momentarily, but first wanted to provide more motivationsfor this specific effort. When teaching thermodynamics on the quarter system, we typicallycover the First and Second Laws of Thermodynamics for both open and closed systems in thirty50-minute class sessions. Due to the rushed nature of this class, there are many fundamentalconcepts which do not get the care and

Teach students to design their own experiments using available equipment to achieve a specified objective.The first four goals can be accomplished with traditional experiments1, in which studentsfollow a specified procedure to generate a clearly-defined set of data. During the first twoyears of their college careers, students encounter this approach numerous times. The fifthobjective, while often an essential skill in professional practice, is seldom considered inintroductory labs. This paper discusses efforts by the Mechanical Engineering faculty atONU to provide a laboratory experience which satisfies all five of these goals by integrating

In the process of developing Rube Goldberg mechanisms, the students areable to practice skills such as communication, teamwork, time and project management, andexperimentation. Rube Goldberg projects also assist in maintaining students’ interest in science,mathematics and engineering. These projects are great way to teach engineering applications ofbasic science concepts such as magnetic induction, gravity, friction, or drag. This paper startswith a background on Rube Goldberg mechanisms and their utilization in engineering education.However, the main focus is given to employment of microcontrollers in Rube

In order to save time, a teaching assistant can begin pre-heating the oil prior to students arriving in the lab. • It is very important to use blenders that have glass pitchers and very tight-fitting lids that form a seal with the pitcher. Plastic pitchers will crack, and ultimately fail, after only one or two uses. Tight-fitting lids will prevent the reaction mixture from leaking out of the pitcher during blending. Laboratory-grade blenders are not necessary, and in some cases, do not have lids that seal and are not large enough to contain the 1200 mL of reactants
