Class Notes Copyright 2005, Walter E. Haisler
When printing the class notes, Word, PowerPoint, etc. documents, you can print multiple pages per sheet on the printer. In Word, Click File on the tool bar, click Print. On the Print box, click Properties and click one of the options of how you want it printed: 1x1, 1x2, 2x2, etc. (similar to PowerPoint). Most post script printers have similar options although the printing option under "Properties" may look different. Saves tons of paper and space in your notebook. IF WORD DISPLAYS THE MACRO VIRUS WARNING WHEN OPENING A DOCUMENT, CLICK "DISABLE MACROS" BEFORE OPENING. This is due to a formating macro imbedded in the file by my version of MS Word, NOT a virus.

Useful Sofware and Links (ENGR 214/AERO 304 related)
Engineering Equation Solver (EES) setup file & EES License file. You must be an engineering student at TAMU in order to obtain and use the EES software which is licensed to the College of Engineering at Texas A&M University. Click on the link here and follow the instructions. Once you obtain the software, install EES by double clicking on the setup_ees.exe icon. This will install EES into a folder called Ees32. Copy the license file (EES.dft) into the Ees32 folder.
MDSolids. Software program that does a lot of "strength of materials" types of problems, i.e., trusses, beam bending and torsion, Mohr's Circle, shear and bending moment diagrams, and a LOT more.
Engineer's Toolbox - A nifty Engineer's Toolbox for structures and materials analysis/design. Runs as a java applet in your browser. Has many useful applications including stress analysis, dynamic analysis, fracture mechanics, numerical analysis and others. You have to register before you can use. The "Engineering Links" should also be useful in your structures courses.
StressAlyzer. StressAlyzer is interactive courseware for learning and practicing solving problems in mechanics of materials. To download, click on the link which takes you to Prof. Steif's web page. To download the program file with Netscape, hold down the shift key while you click the "Download Now" button. Be careful to follow the installation and usage instructions (in the readme.txt file which will be located in the directory where the files will be located when uncompressed). Start with the Load3D module in "review" mode and be sure you read carefully ALL instructions on how to use the program, enter answers, etc. In ENGR 211, you will only be able to use the Load3D modules (problems 1-21). The remaining modues are intended for material in ENGR 214.
West Point Bridge Designer. This program uses truss analysis to help you design various bridge configurations. Go to the link and follow the instructions for downloading and installing the software on your computer (a 4 megabyte file). The developer of the program is LTC Stephen J. Ressler, Civil Engineering Department, West Point Military Academy.
Updated WPBD4.exe file. Find the folder into which the original WPBD4.exe was installed (should be \Program Files\WPBD4, unless you changed the destination during setup), and copy this new WPBD4.exe into that folder, overwriting the old one. You'll know you got it right if the banner says Version 4.0.4, rather than 4.0.3, when you start up the program.
My ENGR 214 web page. See lecture notes on Conservation Principles (mass, linear and angular momentum, energy), strength of materials topics, heat transfer, etc. covered in ENGR 214. Also other links to useful to stuff.
A ton of other fun software (primarily for ENGR 214) may be found at http://aero.tamu.edu/engr214 . But a lot of stuff for ENGR 211 may also be found there. Click on Multimedia; then click the ENGR 211 link. For a truss analysis program, click on "Design Your Own Truss" or go directly there with this link http://www.jhu.edu/~virtlab/bridge/truss.htm. This program is web-based and allows you to analyze any statically determinate two-dimensional truss to obtain the member forces. Try some of the other links like the MATLAB truss program or the online statics tutorial.
Some Very Useful Information for Students
Tips on maintaining confidence, taking tests, understanding different learning styles, and identifying and taking advantage of learning resources on campus. Follow this link to Professor Richard Felder's page for several useful and/or interesting articles for students. Professor Felder is the Hoechst Celanese Professor of Chemical Engineering at North Carolina State University and has contributed over 100 publications to the fields of engineering education and chemical process engineering.
Some Neat Links
|Contains a series of articles written by by Marshall Brain, BYG Publishing, Inc., describing how machinery, engines, electrical and electronic devices, household stuff, etc. work. Written in layman's terms, but very informative; and some of the graphics is very nice.|
