Understanding Bridge Engineering

What is the primary role of a structural engineer in bridge construction?

• To market the bridge to potential investors

• To design the aesthetic aspects of the bridge

• To specialize in designing structures that resist loads

• To supervise construction workers

Which force tries to stretch the bridge components?

• Tension

• Compression

• Bending

• Shear

What makes the Golden Gate Bridge particularly suited to its location?

• Its length

• Its height

• Its ability to withstand earthquakes

• Its color

Which bridge is known as a hybrid of suspension and cable-stayed types?

• Brooklyn Bridge

• Millau Viaduct

• Golden Gate Bridge

• Tower Bridge

What is a key characteristic of arch bridges?

• They primarily resist bending

• They primarily resist torsion

• They primarily resist tension

• They primarily resist compression

Which bridge employs a truss design shaped like an arch?

• Harbor Bridge

• Brooklyn Bridge

• Golden Gate Bridge

• Tower Bridge

What is the purpose of pre-stressed concrete in bridge construction?

• To enhance the aesthetic appeal

• To increase the tensile strength before applying any loads

• To make the construction process faster

• To reduce the weight of the concrete

Which bridge is described as having a 'winking eye' design?

• Sydney Harbour Bridge

• Brooklyn Bridge

• London Bridge

• Gateshead Millennium Bridge

What is a significant challenge in maintaining older bridges?

• Changing architectural trends

• Simultaneous expiration of materials leading to frequent repairs

• High costs of new materials

• Frequent need for repainting

How does the Tower Bridge manage to accommodate both pedestrian traffic and ship passage?

• By using a drawbridge mechanism

• By being exceptionally tall

• By employing a cantilever design

• By using a strong steel composition
