Lesson: Professional Practices

This lesson introduces a step-by-step approach for organizing and solving real-world engineering problems.

Goals

• Apply the MREAC process.
• Explain each concept: dimension, unit, dimensional homogeneity, dimensionless group.
• Apply the grid method.
• Check an equation for dimensional homogeneity.
• Describe the PDM process? What is it? Why is it useful? How do you do it?

Plan (steps to reach the goals)

1. Do EFM9e problems 1.1, 1.2, 1.3.

2. Do the following
a. Review the webpage on the MREAC. What is a MREAC? Why is it useful? How do you create a MREAC?
b. Create a MREAC for "dimension" and for "continuum assumption."
c. What are three useful ideas that you learned about MREACs? Why is the idea useful?

3. Do the following
a. In your own words, explain how to apply the grid method. Do EFM9e problems 1.9, 1.11, 1.12.
b In your own words, explain how to check an eqn. for dimensional homogeneity. Do EFM9e problems 1.4, 1.6.

4. Do the following
a. Explain the PDM process. What is it? Why is it useful? What are the steps?
b. Pick a real-world problem of your choice and solve this problem using the PDM process.

5. Reflective thinking. Think back on your work on this lesson and then answer the following questions.
a. Strengths. Identify the top three actions you took. Name the action, describe what you did, explain why the action was useful to you.
b. Improvements. Identify the top two problems you faced. For each problem, develop problems or challenges did you encounter? Identify your top 2 and for each, identify future actions you will commit to taking. Foryou can take in the future
c. Insights. What the
