Answers to odd problems, 3rd edition Craig
    Note:  This is a zip format file.  On a PC, right click and select extract or uncompress.
    Once uncompressed, the files are in PDF format.  Caution:  I have noticed that not
    all of the answers are correct.


How to Access My Tegrity Videos for Hints and Worked Out Homework Problems

    The format is Microsoft Windows Media Player Version 9.0
    These files are large, and should probably only be used with a high-speed internet connection.
    In Part 1:  I compute (50 - 100)/2 and say +25.  I correct this mistake later in the video.
    If you cannot watch the video, the wording of the problem is the same as problem 8.5-13 plus 8.6-1
    in the textbook.

Mohr's Circle Example:
    Part 1:  The Basics
    Part 2:  The Principal Stress State
    Part 3:  The Maximum In-plane Shearing Stress State
    Part 4:  The Absolute Maximum Shearing Stress
