(Fee: $100) EGME-4810 3 hours Mechanical Engineering Senior Design I –Fa This is the senior capstone design project for mechanical engineers. Student teams work independently on a design project to find a solution consistent with stated specifications using principles studied in previous courses. Work in this semester includes writing the proposal and performing background research and preliminary design. Students conduct a mid-term design review and end-of-semester oral and written presentation. Projects are advised by a faculty committee; course includes weekly written progress reports and meetings with the faculty project advisor. Prerequisites: EGME-3850 Mechanical Design; EGME-3610 Kinematics and Design of Machines; EGME-3150 Heat Transfer; EGME-3020 Mechanical Engineering Lab II; and senior status. (Fee: $100) EGME-4820 3 hours Mechanical Engineering Senior Design II –Sp A continuation of EGME-4810, emphasizing detailed design, prototyping, troubleshooting, design modifications, project completion, reporting, and oral presentation. Students submit written progress reports and attend meetings each week with the faculty project advisor, conduct an oral presentation, and prepare the final report. Prerequisite: EGME-4810 Mechanical Engineering Senior Design I. (Fee: $100) EGME-4950 1-3 hours Advanced Topics inMechanical Engineering Selected topics in mechanical engineering at the 4000-level that expand the depth of existing 3000- and 4000-level courses or expose the students to advanced concepts not taught in other courses. Topics may be proposed by the engineering faculty or students. Prerequisite: instructor’s permission. Every year, the sophomore engineering students participate in the mechanics class competitions. The Dynamics class of Spring 2004 designed and built a baseball catcher, using only coffee-stirring sticks and 1.25 ounces of Elmer’s glue. The catcher had to span a 20-inch support and catch a baseball dropped from 15 feet. Shown above are the first place winners Josh Parker and Daniel Gallagher, who built the lightest-weight successful catcher.
