Considering the ordinary method of slices (OMS) and critical circular slip surface for the slope in
the figure below,
1) subdivide the slide mass into appropriate number of vertical slices;
2) compute the resisting forces (in kips/ft) and show the directions along the slip surface (show
calculations for one example slice and tabulate the remaining slices;
3) compute the factor of safety of this slide mass.
Crest of slope at Elevation 30 ft and toe of slope at Elevation 10 ft. Show all work.
