What is the maximum height (in

\mathrm{m}

) of a brick column of uniform cross section for which column deformation due to its own weight is within the elastic limit?

\left[\mathrm{P}_{\text {atmospheric }}=100 \mathrm{kPa}, \rho=1.8 \times 10^3\right.

\mathrm{kg} / \mathrm{m}^3

. Elastic limit,

\sigma=3.7 \mathrm{MPa}

View answer and explanation

Correct option: A

200

Option D (200) is correct because it is calculated by setting the pressure due to the column's weight equal to the elastic limit and solving for the height.
