Tacoma Narrows Bridge Failure Analysis

The Tacoma Narrows Bridge in Washington collapsed on November 7, 1940, due to design flaws and strong winds. The bridge, known as 'Galloping Gertie,' was too flexible, leading to aeroelastic flutter. Despite attempts to stabilize it, the bridge failed, leaving a lasting impact on engineering practices. The collapse highlighted the importance of aerodynamics in bridge design, leading to stricter testing and design standards.

What was the primary reason for the Tacoma Narrows Bridge's initial design choice?

• To increase its weight capacity

• To reduce construction costs

• To enhance its aesthetic appeal

• To make it the longest bridge in the world

What nickname was given to the Tacoma Narrows Bridge due to its excessive movement?

• Galloping Gertie

• Bouncing Betty

• Swaying Sally

• Wobbling Wendy

What was the outcome of the studies commissioned by the Washington Toll Bridge Authority?

• They were completed and implemented in time

• They were completed but not implemented in time

• They were never completed

• They were ignored completely

What was the main reason for the failure of the hydraulic buffers installed on the bridge?

• They were stolen

• They were never installed

• They were damaged during painting

• They were too expensive to maintain

What was Leonard Coatsworth's main concern after escaping the collapsing bridge?

• The loss of his car

• The damage to the bridge

• The safety of other drivers

• The death of his daughter's dog

What phenomenon contributed to the self-generating movement of the bridge?

• Aeroelastic flutter

• Seismic activity

• Thermal expansion

• Tidal forces

What was the main design flaw of the Tacoma Narrows Bridge?

• It was too short

• It was too flexible

• It was too wide

• It was too heavy

What was left in the water after the bridge collapsed, eventually becoming an artificial reef?

• The bridge's suspension cables

• The wreckage of the roadway

• The concrete pedestals

• The bridge's metal components

What was the fate of the replacement bridge built after the collapse?

• It collapsed again

• It was never completed

• It was demolished for a new design

• It operated without major incident

What was the impact of the Tacoma Narrows Bridge collapse on future bridge designs?

• No significant impact

• Increased focus on aesthetics

• Reduced construction costs

• Mandatory wind tunnel testing
