The soil is clay with C=30 kN/m$^{2}$ and unit weight of 19.7 kN/m$^{3}$. The weight of the chimney is 100 kN and it has a resultant wind load of 25 kN acting at a height of 1.2 m above the ground level acting parallel to both of the sides. Determine the factor of safety with respect to bearing capacity using Vesic's theory.
