1-58 More? See pages 52-56.Steps in engineering problem solving Table 1.7–1(continued)10. Perform a “reality check” on your answer. Does it makesense? Estimate the range of the expected result andcompare it with your answer. Do not state the answerwith greater precision than is justified by any of thefollowing:(a) The precision of the given information.(b) The simplifying assumptions.(c) The requirements of the problem.Interpret the mathematics. If the mathematics producesmultiple answers, do not discard some of them withoutconsidering what they mean. The mathematics might betrying to tell you something, and you might miss anopportunity to discover more about the problem.
1-59 More? See pages 56-60.Steps for developing a computer solution Table 1.7–21. State the problem concisely.2. Specify the data to be used by the program. This is the“input.”3. Specify the information to be generated by theprogram. This is the “output.”4. Work through the solution steps by hand or with acalculator; use a simpler set of data if necessary.5. Write and run the program.6. Check the output of the program with your handsolution.7. Run the program with your input data and perform areality check on the output.8. If you will use the program as a general tool in thefuture, test it by running it for a range of reasonabledata values; perform a reality check on the results.
