ENGR 2143 Strength of Materials – revised 10-Dec-2004

Fall 2004

Department of Physics and Engineering

University of Central Oklahoma

Course Description

This course provides an introduction to solid mechanics, including concepts of stress and strain, mechanical behavior of engineering materials, and analysis of loaded-bearing members.

Prerequisites

ENGR 2033 Statics

Textbook

Mechanics of Materials, Sixth Edition, James M. Gere, Thomson Brooks/Cole, 2004. Please bring your textbook to class for each meeting.

Calculator

You must own a scientific calculator – see the list of allowed calculators for exams in the Department of Physics and Engineering. Please bring your calculator to class for each meeting.

Engineering Paper

Engineering Paper -- available from Thompson's Bookstore or Triangle A&E at Broadway Ext. and 63rd. Please use engineering paper for all homework assignments.

Internet & E-mail

Access to the Internet and ability to send and receive E-mail. If you do not have a computer at home you can use machines on the UCO campus: Look at

for a full list of available general use computers on campus.

Portable Electronic Devices (including cell phones)

Please turn off any portable electronic devices (esp. cell phones) during class. You may not access any portable electronic device during exams except calculators that are on the approved list for Physics and Engineering courses.

Objectives

The student shall be able to

Calculate the stress and strain in loaded two-force members.

1. Demonstrate understanding of stress and strain diagrams for engineering materials and of the application of Hooke’s and Poisson’s laws to loaded members.

2. Calculate stresses in axially loaded members.

3. Calculate stresses in tosionally loaded members.

4. Calculate stresses in flexurally loaded members.

5. Calculate shear stresses in loaded members.

6. Use stress and strain transformation theory and Mohr’s circle to calculate principle stresses in loaded members.

7. Analyze and design beams and shafts.

8. Calculate deflections of beams and shafts.

9. Demonstrate understanding of the application of energy methods to the analysis of beams and trusses.

Instruction Techniques

Lecture will be used predominantly although sometimes recitation periods will be employed.

Class Polices

Attendance is not required, but you will responsible for any announcements or notes from class (and quizzes).

Attendance is mandatory for all exams or other graded activities (e.g. project competitions or presentations).

Cheating or academic dishonesty of any kind will not be tolerated.

Homework

Working HW problems in a timely manner is the best way to do well on exams and in the class as a whole. Homework is due at the beginning of the class period on the due-date or due-day. Homework should be neatly written on only one side of your paper, folded length-wise with your name written on the outside of the folded pages before turning it in. Each problem should fit all of the following criteria: clearly labeled, one problem per sheet of paper, legible and organized. HW papers that do not fit these criteria will be penalized accordingly. See the attached HW Format section for details on the presentation of HW problems. You may also visit the following site for an electronic version of the homework format requirements:

http://engrphys.lemley.org/courses/hwk_format.php

Each HW problem you turn in is worth ten points. Some problems will be graded on detailed solutions and others will be graded on effort. I will not tell you ahead of time which or how many problems will be graded relative to a detailed solution, but on the returned and graded HW paper a check mark next to the problem number will indicate full effort (or ten points) and a numerical score (e.g. 8/10) next to the problem number will be used on those problems under more scrutiny.

Project (cancelled)

There will be a Team Design Project in the last third of the semester. This project will constitute 15% of your grade (the equivalent of one exam). You will receive a hand-out describing your project roughly midway through the semester.

Grading Policies
