Mechanics of MaterialsFor undergraduate Mechanics of Materials courses in Mechanical, Civil, and Aerospace Engineering departments. Hibbeler continues to be the most student friendly text on the market. The new edition offers a new four-color, photorealistic art program to help students better visualize difficult concepts. Hibbeler continues to have over 1/3 more examples than its competitors, Procedures for Analysis problem solving sections, and a simple, concise writing style. Each chapter is organized into well-defined units that offer instructors great flexibility in course emphasis. Hibbeler combines a fluid writing style, cohesive organization, outstanding illustrations, and dynamic use of exercises, examples, and free body diagrams to help prepare tomorrow's engineers. |

... axes are chosen as principal axes of inertia for the area . For an arbitrarily shaped area , the orientation of the principal axes can always be determined , using either the inertia transformation equations or Mohr's circle of inertia ...
... axes of the cross section . When this occurs , the moment should first be resolved into components directed along the principal axes . The flexure formula can then be used to determine the normal stress caused by each moment component ...
... axes . We will now determine the orientation of these axes about which the moments of inertia for the area , I , and I , are maximum and minimum . This particular set of axes is called the principal axes of inertia for the area , and ...
