Overview
The goal of this text is to introduce a general problemsolving approach for the beginning engineering student. Thus, Introduction to Engineering Analysis focuses on how to solve (any) kind of engineering analytical problem in a logical and systematic way. The book helps to prepare the students for such analytically oriented courses as statics, strength of materials, electrical circuits, fluid mechanics, thermodynamics, etc.

What is analysis? A dictionary definition of analysis might read something like this:
An examination of a complex system, its elements,
and their relationships.
Based on this general definition, analysis may refer to everything from the study of a person's mental state (psychoanalysis) to the determination of the amount of certain elements in an unknown metal alloy (elemental analysis). Engineering analysis, however, has a specific meaning. A concise working definition of engineering analysis is
using mathematics and principles of science.
Engineering analysis relies heavily on basic mathematics such as algebra, geometry, trigonometry, calculus, and statistics. Higherlevel mathematics such as linear algebra, differential equations and complex variables may also be used. Principles and laws from the physical sciences, particularly physics and chemistry, are key ingredients of engineering analysis.
Engineering analysis involves more than searching for an equation that fits a problem, plugging numbers into the ation, and "turning the crank" to generate an answer. It not a simple "plug and chug" procedure. Engineering analysis requires logical and systematic thinking about the engineering problem. The engineer must first be able to state the problem clearly, logically, and concisely. The engineer must understand the physical behavior of the system being analyzed and know which scientific principles to apply. He or shemust recognize which mathematical tools to use and how to implement them by hand or on a computer. The engineer must then be able to generate a solution that is consistent with the stated problem and any simplifying assumptions. The engineer must then ascertain that the solution is reasonable and contains no errors.
Engineering analysis may be regarded as a type of modeling or simulation. For example, suppose that a civil engineer wants to know the tensile stress in a cable of a suspension bridge that is being designed. The bridge exists only on paper, so a direct stress measurement cannot be made. A scale model of the bridge could be constructed, and a stress measurement taken on the model, but models are expensive and very timeconsuming to develop. A better approach is to create an analytical model of the bridge or a portion of the bridge containing the cable. From this model, the tensile stress can be calculated.
Engineering courses such as statics, dynamics, strength of materials, thermodynamics, and electrical circuits that focus on analysis are considered core courses in the engineering curriculum. Because you will be taking many of these courses, it is vital that you gain a fundamental understanding of what analysis is and, more importantly, how to do analysis properly. As the bridge example illustrates, analysis is an integral part of engineering design. Analysis is also a key part of the study of engineering failures.
Engineers who perform engineering analyses on a regular basis are referred to as engineering analysts or analytic engineers. These functional titles are used to differentiate analysis from the other engineering functions such as research and development (R&D), design, testing, production, sales, marketing, etc. In some engineering companies, clear distinctions are made between the various engineering functions and the people who work in them. Depending on the organizational structure and the type of products involved, large companies may dedicate a separate department or group of engineers as analysts. Engineers whose work is dedicated to analysis are considered specialists. In this capacity, the engineering analyst usually works in a support role for design engineering. It is not uncommon, however, for design and analysis functions to be combined in a single department because design and analysis are so closely related. In small firms that employ only a few engineers, the engineers often bear the responsibility of many technical functions, including analysis.
