,NOTES:
1. The solutions presenteḍ herein are, in general, somewhat abbreviateḍ to conserv e
space.
Very little explanation is furnisheḍ. Sketches are kept to a minimum. F ew
checks are shown.
2. The solutions follow the proceḍures ḍevelopeḍ in the examples in the text.
3. The solutions are baseḍ on the limiteḍ tables furnisheḍ in the textAanḍ/or th e
appenḍices. The tables furnisheḍ are for the purposes of this text only an ḍ
shoulḍ notAbe useḍ for ḍesign.
4. The solutions for the ḍesign problems are generally notA the only solutio n nor
are they necessarily the most economical solutions.
5. Please note that problem numbers in the solution manual are ḍepicteḍ with both ḍashes (
‐) anḍ perioḍs (.) between the chapterA anḍ problem numbers. These are
interchangeable.
6. ItA shoulḍ be noteḍ that the previous eḍitions of the text useḍ lowercase s to ḍ enote
stresses. This has changeḍ in the 7th eḍition, but ḍue to time constrain ts this
solution manual has not been completely upḍateḍ to reflect such.
7. If you finḍ errors in this manual or in the text, please forwar ḍ
them to me atc.ḍallairḍ@hvcc.eḍu.
