PLEASE NOTE: Please check for changes in homework assignment due dates before working your next problems. They sometimes change.
NOTE ALSO THAT AS THE SYLLABUS CHANGES (AND IT ALWAYS DOES), YOU WILL HAVE TO RELOAD IT, OR IT WILL GO INTO YOUR COMPUTER’S CACHE AND GIVE YOU THE ONE YOU LOOKED AT LAST WEEK , I.E. THE OLD OUT-OF-DATE ONE.
Professor: Lee L. Lowery, Jr., PhD, P.E.
NOTE: My office hours as listed here are suspended on days before a major exam, giving me time to make it out. Please do not wait until the day before a major exam for help. Plan to see the tutors, or me earlier in the week.

Note that less expensive International Editions are often available, but they are sometimes in all SI units, whereas in the U.S. edition, all example problems and half of the homework problems are U.S. customary units. For the 5th edition, I have found that an international edition is available the same as ours, except sometimes the homework problem numbers are changed.
|Texas A&M University Bookstore Fill in the Department, Course, and section number|
|CampusBooks4Less.com – Turns out that their International edition last semester was identical to the U.S. edition that we are using. I just bought it. Cost ~ $43 new, paperback, no color. Check the ISBN number carefully, and be ready to return it. These can be a gamble.|

Course Schedule: Please note that the course syllabus will be revised throughout the semester. Please do not work problems very far ahead of the date due. Some may be dropped, others that are better (in my opinion) may be substituted.

Use of influence lines to determine where to put live, dead, uniform, concentrated loads and compute maximum results.
Notes: The first influence lines are to be generated by statics. All later influence lines can be worked by statics or by Mueller-Breslau if it is to your advantage.
All values are required on all influence lines for statically determinate structures unless otherwise noted. Numeric values on statically indeterminate structures are not required – only the shape of the influence diagram.
