Resonance

Natural frequency is best described as

• the frequency at which an object naturally vibrates at when it is disturbed

• a vibration that can be heard in the wild

• the radio frequency that astronauts naturally use when travelling into space

• the material used to make a swing

How does resonance affect the design of bridges?

• Engineers must ensure that the natural frequency of the bridge does not match the frequency of external forces like wind or traffic

• Resonance is used to enhance the aesthetic appeal of the bridge

• Resonance is ignored in bridge design

• Resonance is used to increase the weight capacity of the bridge

What is the relationship between resonance and damping?

• Damping reduces the amplitude of resonance

• Damping increases the frequency of resonance

• Damping has no effect on resonance

• Damping amplifies the resonance effect
