Engineering Failures and Lessons Learned

The video explores various engineering failures, including the Tay Bridge, Quebec Bridge, Tacoma Narrows Bridge, Hyatt Regency skywalks, Citicorp Tower, and Millennium Bridge. Each case highlights different engineering challenges and the lessons learned from these failures. The video emphasizes the importance of thorough inspections, understanding structural limits, and the role of unforeseen factors in engineering design.

What was the main reason for the excitement among scientists when an experiment doesn't go as planned?

• It's a chance to prove their hypothesis wrong.

• It's an opportunity to learn something new.

• They can get more funding.

• They can publish more papers.

What was a significant factor in the collapse of the Tay Bridge?

• The bridge was built in a desert.

• The bridge was too short.

• The bridge's components couldn't withstand the pressure.

• The materials used were too strong.

What was a significant outcome of the Tay Bridge disaster?

• All bridges were made of wood.

• Bridges were built shorter.

• Bridge inspections became more thorough.

• Bridges were no longer built in Scotland.

Why did the Quebec Bridge collapse during its construction?

• The workers were inexperienced.

• The support pieces were bent more than they should have been.

• It was built on unstable ground.

• It was hit by a large ship.

What was the primary cause of the Tacoma Narrows Bridge collapse?

• A strong earthquake.

• Aeroelastic flutter.

• A large truck crossing the bridge.

• Heavy snowfall.

What lesson was learned from the Tacoma Narrows Bridge collapse?

• Bridges should not be built over water.

• Bridges should be tested for aeroelastic flutter.

• Bridges should be built wider.

• Bridges should be made of wood.

What was a key design flaw in the Hyatt Regency walkways?

• They were made of wood.

• They were supported by weak pillars.

• They were too short for the building.

• The rods were changed to hold more weight than intended.

What was the main issue with the Citicorp Tower that was discovered after its construction?

• It was unstable in strong winds.

• It was built on a fault line.

• It was made entirely of glass.

• It was too tall for the area.

How was the Millennium Bridge issue resolved?

• By adding dampers to absorb pedestrian steps.

• By closing it permanently.

• By reducing the number of people allowed on it.

• By adding more weight to the bridge.

What was the main reason for the Citicorp Tower's potential instability?

• The building was too short.

• The building was made of glass.

• The stilts were placed in the middle of its sides.

• The building was too light.
