May 2010

792 pages


Philpot helps engineering students visualize key mechanics of materials concepts better than any text available, following a sound problem solving methodology while thoroughly covering all the basics. The second edition seamlessly integrates the author’s award winning Mecmovies software with the chapters. It incorporates approximately 150 new problems to help students learn how to apply the material. New coverage is included on discontinuity functions. Content has also been revised throughout the text to provide students with the latest information in the field.

 Homework Problems

  • Revised 40% of end of chapter problems
  • Added additional homework problems, approx. 150 new problems across all chapters.
  • Communicating visually- The illustrations use color, shading, perspective, and dimension to clearly convey concepts while striving to place these concepts in the context of real world components and objects.  These illustrations have been prepared by an engineer to be used by engineers to train future engineers.
  • MecMovies-The text integrates computer based instruction into the traditional textbook format with the addition of the MecMovies instructional software.
  • Problem-solving schema- The textbook and software include a number of multimedia features aimed at helping students organize and categorize the Mechanics of Materials concepts and problem-solving procedures. 
  • Style and clarity of examples- To a great extent, the Mechanics of Materials course is taught through examples, and consequently, this textbook places great emphasis on the presentation and quality of example problems.  The commentary and the illustrations associated with example problems are particularly important for the learner.  The commentary explains why various steps are taken and describes the rationale for each step in a solution process while the illustrations help build the mental imagery needed to transfer the concepts to differing situations.
  • Homework philosophy- This textbook includes over 1080 homework problems in a range of difficulty suitable for learners at various stages of development. Problems have been designed with the intent of building the technical foundation and skills necessary for success in subsequent engineering design courses.  The problems are intended to be challenging but at the same time practical and pertinent to traditional engineering practice.
