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HAVE TO RELOAD IT, OR IT WILL GO INTO YOUR COMPUTER’S CACHE AND GIVE YOU THE ONE YOU LOOKED AT LAST WEEK , I.E. THE OLD OUT-OF-DATE ONE.

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. |

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. |
