Engineering lesson 20: Types of bridges · Set 5 · 40 questions

Engineer's tip (How does it hold up?): Beam: flat deck on supports, short spans; spans = length ÷ span length. Arch: curved, in compression, pushes out on its ends. Suspension: deck hangs from cables (tension) over towers (compression); longest spans.
