A cut has to be made 14m deep, inclined at an angle 45$^{\circ}$ to the horizontal.
... The possible slip surface has a radius equal to 22 m, and passing through the toe of cut slope and trough the point 3.6 m away on the top ground from the edge of cut. The C.G of failure mass is 10.3 m from the center of failure circle. The properties of soil are C = 50 kN/m$^{2}$, $\phi=15^{\circ}$ ...

A chimney with a rigid base 2.5 m square footing is placed at a depth of 1.2 m below the ground level.
... 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 capa ...
