Bridge Engineering Quiz

Which force is primarily responsible for stretching materials in a suspension bridge?

• Compression

• Tension

• Torsion

• Shear

What shape is most commonly used in truss bridges due to its stability?

• Square

• Triangle

• Circle

• Hexagon

Why are arches effective in bridge construction?

• They reflect tension

• They distribute load as compression

• They absorb vibration

• They increase surface area

Which bridge type can span the longest distances without support?

• Arch

• Truss

• Suspension

• Beam

What is the weakest point in a cantilever bridge if not properly reinforced?

• The support tower

• The hinge

• The suspended span

• The abutments

Which of the following materials has the highest tensile strength?

• Concrete

• Wood

• Steel

• Brick

Which component resists bending in a beam bridge?

• Deck

• Piers

• Girders

• Ropes

What is one disadvantage of using concrete without reinforcement?

• It's too light

• It can't resist compression

• It cracks under tension

• It absorbs water easily

What type of bridge uses tension and compression most efficiently together?

• Arch

• Truss

• Suspension

• Beam

What happens if load exceeds the yield strength of a bridge material?

• It becomes more elastic

• It returns to shape

• It deforms permanently

• It resists the load better
