How do earthquakes of different strengths affect buildings of different heights?
Why is it that short buildings respond more to high frequency oscillations while tall buildings respond more to low frequency oscillations?
I would assume that how they react is related to the natural ...

Finding a single component of a strain tensor ($E_{yy}$) knowing $E_{xx}$ and $E_{yx}$
I know $E_{xx}$, $E_{yx}$, and $E_{xy}$ but I can't figure out how to find the value for $E_{yy}$. I think it has something to do with the phrase 'homogenous $2D$ strain' as a big hint since there's ...
