Engineering Worksheet: Constraints and Criteria

Engineering lesson 4: Constraints and criteria · Set 127 · 40 questions

Engineer's tip (Limits and goals): Constraint = a limit on money, materials, time or size. Criterion = a goal: what the design must do. Check both with numbers: money left ÷ price for how many you can buy; result ≥ goal for “meets it”.
