1st Edition
Applied Engineering Mechanics Statics and Dynamics
This is the more practical approach to engineering mechanics that deals mainly withtwo-dimensional problems, since these comprise the great majority of engineering situationsand are the necessary foundation for good design practice. The format developedfor this textbook, moreover, has been devised to benefit from contemporary ideas ofproblem solving as an educational tool. In both areas dealing with statics and dynamics,theory is held apart from applications, so that practical engineering problems, whichmake use of basic theories in various combinations, can be used to reinforce theoryand demonstrate the workings of static and dynamic engineering situations.In essence a traditional approach, this book makes use of two-dimensional engineeringdrawings rather than pictorial representations. Word problems are included in the latterchapters to encourage the student's ability to use verbal and graphic skills interchangeably.SI units are employed throughout the text.This concise and economical presentation of engineering mechanics has been classroomtested and should prove to be a lively and challenging basic textbook for two onesemestercourses for students in mechanical and civil engineering. Applied EngineeringMechanics: Statics and Dynamics is equally suitable for students in the second or thirdyear of four-year engineering technology programs.
