Textbook: Erdman, A.G., Sandor, G.N., Mechanism Design; Analysis and Synthesis, Vol. 1, 3rd Edition, Prentice Hall, 1997. Jack, H. EGR 352 Course Notes, GVSU.

Computer Access: The student is expected to be able to use the following software packages.

Working Model, version 4

MathCAD version 7

AutoCAD version 14

Netscape Communicator

FTP/Telnet

Excel

Suitable hardware and software are available in EC 616.

Objectives:

a) To give students a clear understanding of the inner nature of mechanisms and machinery.

b) To stimulate students innovation and creativity in designing mechanisms and mechanical systems.

c) To make use of modern computer based design tools

Instruction Methods: Lectures, projects and discussions.

Grading:

Tests 30%

Assignments 15%

Professional Participation 10%

Final Project 20%

Final Exam 25%

Tests and assignments will be given at natural points during the term as new material is covered. Students will be expected to participate on a professional level during the course, and so individual work will be assigned at times, with expectation that it will be presented to the students/peers during lecture times. A final project, involving construction, will be assigned and tested later in the term. Marks will be some combination of performance and report. A final examination will be given to conclude the work, and test the students global comprehension of the material.
