COURSE - STRENGTH OF MATERIALS - EG202
INSTRUCTOR - NICK BERTOZZI
FALL 2004
COURSE DESCRIPTION
Stress and strain, torsion of circular shafts, Mohr's circle, bending and deflection of beams, combined loading, column buckling, and welded and riveted joints.
Prerequisites: EG200 and MA201
COURSE OBJECTIVE
To extend the student's study of Engineering Mechanics beyond statics to the concepts of stress and strain and deflection. Continued work on problem-solving skills. Students will also become proficient in using finite element analysis software.
TEXTBOOK
Mechanics of Materials, 3rd Edition, by Beer, Johnston, and DeWolf, published by McGraw-Hill, New York, 2002.

OUTCOMES
1) The student will increase their skill in constructing free body diagrams clearly differentiating between the system and surroundings, and external and internal forces and moments.
2) The student will learn and understand in depth the fundamental scientific principles associated with stress analysis and be able to apply these principles skillfully and creatively in the solution of stress and deflection problems and in the design of engineering components.
3) By applying finite element analysis to the computer solid models of their design projects the students will verify their theoretical analyses. They will apply various failure theories to determine factors of safety, evaluate and animate deformations, and determine the best areas to remove material for weight reduction.

ATTENDANCE
In this course you will be expected to act in a professional manner. Among other things this includes showing up on time prepared for the task at hand. It should include not just being on time for class and lab, but also for the additional outside meetings you will have with your design group. To encourage you toward this end, students with perfect attendance will have 3 points added onto their final average. For every unexcused absence you will have 1 point deducted from your final average. (Note that if you are more than five minutes late for class or lab you will be marked absent) On the other hand if I am more than five minutes late for a class, I will add an additional point to the average of each student present.
