Assuming that we wanted to consider building's vertical column, which can be simplified as

axial bar shown below:

$=2\mathrm{.}1\frac{g}{c{m}^3}$

$E=2$GPa

${}_y=55$MPa

g is gravitational acceleration.

Question $7$

For the nominal data provided above, determine the axial displacement at $x=5\mathrm{.}01m$ if

$h_o=10m.$

Express your answer in mm up to $3$ places of decimals.

Question $8$

For the nominal data provided above, determine the stress at $x=7\mathrm{.}3m$ if $h_o=10m.$

Express your answer in KPa up to $2$ places of decimals.

Question $9$

Extending the above idea of building to a very tall tower with target height of $h=1,424m.$ How

much higher this tower needs to be built so that target height is sustained.

Hint: you need to calculate $($h$-$ho$).$

Express your answer in meters up to $2$ places of decimals.
