This introduction provides procedures for approaching an engineering problem, determining the necessary data and method of solution (including engineering estimates, if necessary), and presenting the results using appropriate units. This title is part of the B.E.S.T. series (Basic Engineering Series and Tools) consisting of modularized textbooks offering virtually every topic and speciality likely to be covered in an introductory engineering course. These modules are easily combined with each other to construct an introduction to an engineering course. The goal of this series is to provide the educational community with material that is timely, of high quality, and flexible in how it is used.
