The motion of a 6500-lb boat is arrested using a bumper which provides a resistance as shown in the graph. The coefficient of kinetic friction between the ground and the crate is mk = 0.55. Determine the tension in the cable and the work done by this force. A 1500-lb crate is pulled along the ground with a constant speed for a distance of 25 ft, using a cable that makes an angle of 15° with the horizontal.

Throughout the book, many analysis and design applications are presented, which involve mechanical elements and structural members often encountered in engineering practice.© 2010 Pearson Education, Inc., Upper Saddle River, NJ. The hallmark of the book, however, remains the same as the author's unabridged versions, and that is, strong emphasis is placed on drawing a free-body diagram, and the importance of selecting an appropriate coordinate system and an associated sign convention whenever the equations of mechanics are applied. The development emphasises the importance of satisfying equilibrium, compatibility of deformation, and material behaviour requirements. It provides a clear and thorough presentation of both the theory and application of the important fundamental topics of these subjects that are often used in many engineering disciplines. Statics and Mechanics of Materials represents a combined abridged version of two of the author's books, namely Engineering Mechanics: Statics, 14th Edition and Mechanics of Materials, 10th Edition. For courses in introductory combined Statics and Mechanics of Materials courses found in ME, CE, AE, and Engineering Mechanics departments.
