Which of these is the best example of a specific, solvable engineering problem?
ARecess is too short
BThe classroom is not fun enough
CPapers blow off the outdoor lunch tables when it is windy
DEverything at school is old
Papers blowing off outdoor lunch tables is specific (we know exactly what happens), observable (we can see it), and solvable (we could design a clip, a weighted placemat, or a windscreen). The other options are too vague — what exactly would you build to make recess longer or the classroom more fun?
Question 2 True / False
Engineers should start building a solution before fully understanding the problem so they do not waste time.
TTrue
FFalse
Answer: False
Jumping to building before understanding the problem is one of the biggest causes of engineering failure. If you build a solution to the wrong problem — or to a vaguely defined problem — your work is wasted. Time spent understanding the problem and its constraints saves much more time than it costs.
Question 3 Short Answer
What is a constraint, and why is it helpful when solving an engineering problem?
Think about your answer, then reveal below.
Model answer: A constraint is a rule or limit that a solution must follow, such as a budget, size, weight, or safety requirement. Constraints are helpful because they narrow the options and prevent wasted effort on solutions that would not work in the real world.
Without constraints, engineers would have infinite possibilities and no way to choose between them. Constraints like 'must cost less than ten dollars' or 'must be safe for small children' immediately rule out many options and focus effort on ideas that could actually be used.
