Engineering Worksheet: Final Test

Engineering lesson 24: Final engineering test · Set 554 · 40 questions

Engineer's tip (Find the topic, use the idea): Find the topic: design process, force, machine, lever, structure, material, bridge or scale. Use that lesson’s rule — what is in the middle, load × distance = effort × distance, work = force × distance, real = drawing × scale. Write the calculation before you answer.
