Why Is Communication Important to an Engineer?
As an engineering students you need to develop good written and oral communication skills. As an engineering student and later as an engineer you need to know how to express your thoughts present a concept for a product or a service present an engineering analysis of a problem and its solution, or show your findings from an experimental work © 2011 Cengage Learning Engineering. All Rights Reserved.
6
Why Is Communication Important to an Engineer? (continued)
You need to know how to communicate design ideas by means of engineering drawings or computer aided modeling techniques. Most engineers are required to write reports that may be detailed and lengthy may contain charts, graphs, and engineering drawings, or may be brief and in the forms of progress reports, memorandum, or executive summary © 2011 Cengage Learning Engineering.

Problem Solving – 4 Basic Steps
Defining the problem Simplifying the problem Performing the solution or analysis Verifying the results © 2011 Cengage Learning Engineering. All Rights Reserved.
9
Problem Solving Step 1: Defining the problem Understand the problem
what is being asked what is known what is to be determined © 2011 Cengage Learning Engineering. All Rights Reserved.
10
Problem Solving Step 2: Simplifying the problem
Make appropriate assumptions Understanding the fundamental concepts and physical laws as well as when and where to apply them and their limitations will benefit you in making the correct assumptions © 2011 Cengage Learning Engineering. All Rights Reserved.
11
Problem Solving Step 3: Performing the solution or analysis
Select appropriate model(s) You may need to apply Mathematical concepts Physical laws Engineering fundamentals Show appropriate units You may need to show your results in numerical or parametric forms © 2011 Cengage Learning Engineering. All Rights Reserved.
12
Problem Solving Step 4: Verifying the results
Does the answer make sense? How would you know your answer is correct? Should you ask your professor? Should you check the back of your textbook to match answers You should know the range of answers You should know other ways to analyze the problem You should know how to simplify or approximate the problem for a “ball park” answer © 2011 Cengage Learning Engineering. All Rights Reserved.
13
Homework Presentation
All homework presentation should include: Given: Problem statement Extracted information Find: What is to be determined? Solution Appropriate model(s) diagrams Step by step calculations Answers with proper units highlighted © 2011 Cengage Learning Engineering. All Rights Reserved.

Progress Report A short form of communication to others in an organization or to the sponsors of a project Work completed so far Work expected to be completed during the next reporting period Any problems that may have come up, and the recommended solutions © 2011 Cengage Learning Engineering. All Rights Reserved.
17
Executive Summary A brief and concise form of communication to top management To convey the findings of a study or proposal Typically few pages long References may be made to more comprehensive reports © 2011 Cengage Learning Engineering. All Rights Reserved.

22
Technical Report – Objectives
State what is to be investigated List your objectives explicitly, for example, 1. , 2., 3., © 2011 Cengage Learning Engineering. All Rights Reserved.
23
Technical Report – Theory and Analysis
To state pertinent principles, laws, and equations (equations should be numbered) To present analytical models used To define unfamiliar terms and symbols To list important assumptions © 2011 Cengage Learning Engineering. All Rights Reserved.
24
Technical Report – Apparatus and Experimental Procedures
To present the list of apparatus and instrumentation used (include instrument range, accuracy, and ID number) To describe how you performed the experiment The experimental procedure should be itemized Include schematic diagram of the experimental setup © 2011 Cengage Learning Engineering. All Rights Reserved.
25
Technical Report – Data and Results
Present the results of the experiment in tabular or graphical forms The tables and graphs must include titles, column or row headings, units, axis labels, and data points clearly marked All figures and tables must be numbered and have descriptive titles All figure numbers and titles should be placed below the figures. All table numbers and titles should be placed above the tables. © 2011 Cengage Learning Engineering. All Rights Reserved.
26
Technical Report – Discussion of the Results
Emphasize and Explain to the reader the important results of the experiment. When applicable, compare experimental results with theoretical calculations © 2011 Cengage Learning Engineering. All Rights Reserved.

Visual Aides PowerPoint Use colorful charts, graphs, & tables
Use appropriate contrast Use large fonts Don’t overcrowded the “slide” Use short phrases instead of paragraphs If available, use models and prototypes If possible, use video clips and animations © 2011 Cengage Learning Engineering. All Rights Reserved.
34
An Example of Animation
mechanical work is defined as the component of the force that moves the object times the distance the object moves more in physics, mechanics of materials, structural analysis & others work = F x d unit: N-m, j, lb-ft…. distance, d force © 2011 Cengage Learning Engineering. All Rights Reserved.
35
Engineering Graphical Communication
More in chapter 16 Engineers used engineering drawings to convey their ideas and design information about products Engineering drawings portray vital information such as shape of the product, its size, type of material used and assembly steps Machinists use the information on the engineering drawings to make the parts © 2011 Cengage Learning Engineering.

Summary You should know the basic steps involved in the solution of engineering problems. You should realize that you must find your own ways to verify your solutions to a problem. You should realize that it is very important for engineers to know how to communicate well with others both orally and in written form. You should be familiar with various ways of giving an engineering presentation. © 2011 Cengage Learning Engineering. All Rights Reserved.
