Question

Earth quakes near the California Bay typically occur at frequencies of 1.5HZ or 2.8HZ. If you were engineering a new building in that area, choose the natural frequency you would want your building to have so that it would be least likely to collapse during an Earthquake.

a. 2.0 Hz

b. 1.6 Hz

c. 2.7 Hz

Answer 1

Answer:

2.0 Hz

Explanation:

2.0 Hz is the most closest to the middle number in between 2.8 and 1.5 Hz. 1.6 Hz would not be suitable as it is too close to 1.5 Hz and 2.7 would also not be suitable as it is too close to 2.8 Hz.
