Lecture: M/W (50 minutes/lecture)
-
Discussion: R (two hours), four small groups of about 22 students each
- Contribution of course to meeting the professional component
- This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.
The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.
-
-
This course is central to developing students ability to analyze, design and/or select machine elements and therefore involves economic, societal, safety and manufacturing aspects. In addition to technological considerations, the team projects help develop ability to work in teams, address open-ended engineering problems and written communication via reporting the results.
- Relationship of course to undergraduate degree program objectives and outcomes
- This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.
-
-
The course builds on the students' previous fundamentals in mathematics, science and engineering to help develop mechanical design methodology. ME 342 provides an extremely important preparation for the capstone design courses in the Mechanical Engineering curriculum.
- Assessment of student progress toward course objectives
-
Two two-hour midterm examinations plus a two-hour final examination
-
Weekly homework assignment are required and graded
-
Several team projects. Teams consist of 3 to 5 students each. The assigned problems/projects are somewhat open-ended, and the required reports are graded on technical content and format/quality of presentation, etc.
