A cut slope is to be made in a clayey soil to permit construction of a new highway as shown below. A slope stability analysis is to be performed along the potential shear surface shown in the figure. The soils are silty clays with c' = 18 kPa, phi’ = 20degree. If the shear stress at point A is 60 kPa, compute the factor of safety against sliding at A.
