1. Pentium-based PC
2. Microsoft Windows 95 with OSR2 (Windows 95B) or better, Windows 98, or Windows 95  NT 4.0 with Service Pack 3 or 4.  To check which operating system is running, right-mouse-click on the "My Computer" icon and select properties. After clicking on the "General" tab, look at the "System" information which contains the operating system and its release version. If your computer is running Windows 95A, you need to upgrade your operating system.
3. 64 MB RAM or better
4. 160 MB of free space on the hard drive
5. VGA 800 x 600 resolution or better
6. Video card and monitor capable of displaying at least 256 colors  and, preferably, with more than 4MB of video RAM
7. CD-ROM drive
8. Web browser (e.g., Netscape 3.0 or better, or Internet Explorer 4 or better)
9. Media/movie player (e.g., Windows Media Player, AVI player)
10. Sound card and speakers (optional)
 

1. Double-click on Setup.exe in the root directory of the CD and follow the installation instructions.

2. By default, the installation installs the Working Model View program, the content navigation html files, and the Working Model 3-D Simulations exercises onto your hard drive. You will also be given the option to install the movie DemoMovie.avi. The content navigation html files are viewed as web pages and provide instructions for using Working Model View, running the Working Model 3-D Simulations exercises, and other goodies such as movies, problem statements, and FAQ.  Note that you can always install files later by double-clicking on Setup.exe on the CD and selecting the proper components to install.

3. After installation is completed, restart your computer.

4. Immediately launch Working Model View so that the computer associates the Working Model files with the Working Model View program.  If association does not occur after starting Working Model View, e.g., icons for Working Model files do not appear as gyroscopes, restart the computer.

5. Before sampling the exercises on the CD and exploring the rest of the content, we suggest that you view the movie. Double-click on DemoMovie.avi in the root directory of the CD.

6. Begin exploring the Working Model 3-D Simulations exercises by opening the file StartHere.html using either Netscape Navigator (preferred) or Internet Explorer. The file StartHere.html is located in the folder WorkingModel3DSimulations in the root directory of your hard drive, or in the folder you specified during installation.
 
Note for Microsoft Internet Explorer users: Because of bugs in Internet Explorer, Working Model View has a long idle period before opening a Working Model file from within Internet Explorer. To avoid this long delay, click on IE Jump Start which is located on the left-side frame of StartHere.html.  You will be prompted to open or save a file, select open.  After doing this once, you should experience no more delays in opening Working Model View files in Microsoft Internet Explorer.

7. To go directly to playing with the Working Model 3-D Simulations exercises, open the folder WorkingModel3DSimulations\Exercises. Inside that folder, you should see a list of files with the extensions .wm3. The .wm3 files are the Working Model 3-D Simulations exercise files. Open any of the .wm3 files by double-clicking on it.

8. Because the exercises have been designed to supplement the Beer & Johnston textbook, we recommend that you have the textbook in front of you when you explore them. To maximize the utility of the exercises, read the problem statement and steps of the solution in the textbook before running the exercises.

9. Finally, if you have other questions (e.g., how to use Working Model View), read the rest of this page and the FAQ page. Working Model help is also available by invoking Working Model View and selecting an option under the Help menu.
 

For best viewing result, use a screen resolution of 800 pixels x 600 pixels. To change screen resolution, right-mouse-click on your computer screen's background, select Properties, click on the Settings tab, slide the control bar to 800 x 600, and follow instructions for testing/applying these settings. (Note: You may reset the screen resolution when you are finished.)
 

After installing Working Model View, launch the program from the Start menu. changing the screen resolution to the proper setting, you can load and run Working Model files. There are three ways to do this:

1. To start Working Model View, go to the Start button on the bottom left-hand corner of your computer screen, select Programs, then Working Model, then Working Model View. Click on Open under the File menu to open the .wm3 ( the file extension associated with Working Model View) file you want in the Exercises folder. This folder is located in the target directory specified during installation. (Note: The default location during installation is C:\WorkingModel3DSimulations) A second copy of this folder (and files) is located on the Working Model 3-D Simulations CD.

2. Using the Windows Explorer, open the directory containing the Working Model file (Working Model files are named with a .wm3 extension) and double-click on the relevant .wm3 file. This will invoke Working Model View and load the selected .wm3 file.

3. With Netscape Navigator or Internet Explorer, you can use this HTML document as a launching point for viewing Working Model files. Located in the side frame of this HTML document is a list of chapters. Click on a chapter and scroll to a problem; click on the link to the problem statement, and then click on the link to the .wm3 file. (Note: You can use Internet Explorer to view .wm3 files, but we have found severe deficiencies in it. It can take more than 35 seconds to open Working Model View or other non-Microsoft programs. To remedy this problem, click on IE Jump Start on the left side frame before running Working Model files.)
 

1. Change your view of the system.

2. Vary parameters via slider controls.

3. Control how the simulation proceeds, i.e., run, stop, rewind, fast-forward, replay, advance one frame, and move back one frame.

4. Obtain measurements in the form of numbers or plots.

5. Create comments/annotations of the simulation.

Instructions for these features can be found in the Help menu in Working Model View. See the FAQ page for additional information.
 

There are step-by-step instructions in every Working Model 3-D Simulations file. For example, the following instructions are displayed when SampleProblem02.01.wm3 is opened.

1. Press Run (Play).
2. Vary the magnitude of force Q.
3. Observe the effect on the resultant force R.

1. To run (play) a Working Model file, click on the green "Play" button that is located on the bottom left hand side of the Working Model window. Located adjacent to the Play button are other common "VCR" controls. From left to right, these are

a. Reset (brings the demo back to the beginning)
b. Backward Play (runs the demo backward; only works after the demo has run forward)
c. Stop (stops the demo at the frame at which the button is pressed)
d. Run/Play (runs the demo)
e. Control Bar (wide horizontal bar that shows simulation progression)
f. Rewind (run backward one frame)
g. Forward (run forward one frame)

3. To modify the value of a parameter controlled by a slider (e.g., force Q in the example above), move the slider left or right. To enter a numerical value for a parameter, click on the edit box on the left-hand side of the slider and type in a value.

4. When running a simulation, you can change the value of the slider as long as the simulation is playing for the first time (not doing a replay). To start over, press CTRL-H (erase history), enter new slider values, and press Play.

5. After saving a Working Model file, you may notice that the file's size is much larger than the original one. This is usually due to the fact that you did not Reset and press CTRL-H (erase history) before saving the file.
