Solving Engineering Problems Step by Step

This is the first of many videos I hope to be making as I review for the FE exam. This first video is about the general approach to solving a typical engineering problem. The five “easy” steps and are consistent with what might be expecting in homework or on a test. I’m trying to determine what might be best to start with, maybe chemistry or circuits?





Here is a recap:

Step 1: Read or define the problem.

• Briefly describe the problem or what you seek to know.
• Note the given/known information.
• Understand and make clear your objectives.

Step 2: Draw a schematic/diagram of the problem.

• Keep is simplified and relevant to the problem
• Include key features.
• Label important information.

Step 3: State assumptions and approximations.

• Keep track of simplifications.
• Present reasonable values for required information.
• Mention physical laws.

Step 4: Begin calculations.

• Write down relevant equations.
• Solve and simplify equations as much as possible before substituting.
• Mind your units and significant digits.

Step 5: Most important! Critique your answers.

• Check to see if answers make sense.
• Mention key points for the future you.
• Mention important limitations for answer.

Rinse and repeat!
