Question

If $\rho$ is the specific gravity of the material used in the design of a masonry dam of triangular section, then the ratio between the height and base width of the dam for structural safety and stability is equal to

• A. $\sqrt{2\rho }$
• B. $\sqrt{\rho }$
• C. $\frac{1}{\rho }$
• D. $\frac{1}{\sqrt{\rho }}$

Answer 1

The correct option is B $\sqrt{\rho }$

$\frac{H}{b}=\sqrt{\rho }\text{from stress criterion}$

$\frac{H}{b}=\mu \rho \text{from stability or sliding criterion}$
