2. Catalogue Description (2001-2003 Undergraduate Bulletin)
Design process, review of stress, strain and deformation analysis as applied to mechanical design; properties of materials; review of static failure theories; designing against fatigue failures; element design; shafts, keys, couplings, power screws; bolted, riveted and welded joints.
3. Prerequisite Knowledge and/or Skills
- Free-body diagram - Force and moment equilibrium
- Stress-strain response and Hooke's law - Force, moment and torque diagrams
- Normal and shear stresses in beams and shafts - Mohr s circle & transformation eqs.
- Stress concentrations - Concept of work and power
- Computer graphics - Spreadsheets
4. Course Objectives
To help introduce the student to the design of mechanical elements, to incorporate knowledge learned in the mechanics, structure and manufacturing courses, to reinforce competence in multi-axis stress analysis and understand the importance of using and interpreting Mohr s circle, to develop competence in using the proper failure theories under steady and variable loadings, to master the design of mechanical elements such as shafts, couplings, power screws, detachable and permanent connections.

7. Assignments
Homeworks: Problem sets will be assigned from the textbook and elsewhere.
You are expected to work on the homework individually.
Homeworks should be submitted in the class on the due time.
Project: One or more design projects will be proposed for students to work on early
in the semester. A final design report should be presented before the set
deadline, two weeks before the end of classes.
Homeworks and Project report should be submitted in a proper format. Students should adhere to the Guidelines for Writing a Professional Design Report which will be distributed to them early in the semester.
8. Computer Usage
· Students will need to use computers to solve homework problems, since open-ended and iterative problems will be usually assigned.
· The design project is expected to rely on heavy usage of computers as well.
· You may use any software package you are most familiar with. SolidWorks, SolidEdge and EXCEL are possible ones. In due time, you will also be provided with some commercial or in-house programs to help you with the design process.
9. Examinations
The Major and Final Examinations will be open book. You will be allowed to prepare one single sheet listing all important formulae that you need.
Major Examination 1 October 25, 2004 Monday 9-11 pm;
Location: TBA
Major Examination 2 December 12, 2004 Sunday 7-9 pm ;
