VECTOR MECHANICS FOR ENGINEERS
Continuing in the spirit of its successful previous editions, the ninth edition of Beer, Johnston, Mazurek, and Cornwell’s Vector Mechanics for Engineers provides conceptually accurate and thorough coverage together with a significant refreshment of the exercise sets and online delivery of homework problems to your students. Nearly forty percent of the problems in the text are changed from the previous edition. The Beer/Johnston textbooks introduced significant pedagogical innovations into engineering mechanics teaching. The consistent, accurate problem-solving methodology gives your students the best opportunity to learn statics and dynamics. At the same time, the careful presentation of content, unmatched levels of accuracy, and attention to detail have made these texts the standard for excellence.
- Overall It was a useful book. Chapters 1-3 were too wordy for my taste, and really suffered from poor organization. There is a lot of referencing figures not on the page throughout the book, however once you get into the meat of the book (chapter 5+) it really streamlines and becomes a valuable study aid.
- It’s worth it to by the soft cover for this class, its not missing any material and will save you some good bucks.
- The text by Gere and Goodno is a current version of the study of Strength of Materials, that element of Statics and Structures which considers the effects of loads on structures and ascertaining the maximum carrying capacity.
There are three main elements in understanding the subject:
1. Understanding the basic elements of statics; namely i. the sum of forces and moments equal zero, ii. stress is a force per unit area, iii. strain is a multiple of stress unless it is no longer so.
2. Applying geometry and trigonometry to static systems. This means having a good grasp of angles and distances so as best to allocate loads.
3. Paying attention to units. There is often a plethora of mixed units from lbs, N, kg, g, Pa, etc thus must be equated and often lead to either over or under stating the results.
That is it. There frankly is not much more. Like books covering this material for well over a hundred years this text does so as well. The coverage includes:
1. Stress and strain principles.
2. Applications to beams and cylinders. This is where getting the geometry correct starts to become important.
3. Bending of beams. This is the classic analysis of beams and determining maximum stress and seeing if one’s design is well within limits.
4. Columns and similar structures.
5. Indeterminate structures, the ones where there are an excess of givens.
6. Collapse and breakage.
