Question
Because they reduce vibrations, tuned mass dampers protect skyscrapers against winds and these events. For 10 points each:
[10e] Name these natural events that can be simulated on small scales by shake tables.
ANSWER: earthquakes [or seismic events or seismic activity]
[10h] In this method in earthquake engineering, elastomeric dampers made of rubber or sliders are used to separate a building's foundation from its superstructure.
ANSWER: base isolation [or seismic isolation]
[10m] The seismic type of these materials can be engineered to redirect seismic waves, analogously to how the left-handed type of these materials can redirect light waves due to having a negative index of refraction.
ANSWER: seismic metamaterials [accept left-handed metamaterials]
