ABSTRACT
These factors are the values used to plot point 1 in the graph in Fig. 10.15(b). Similarly other friction circles with radii KR sin l/J'm2' KR sin l/J'm3' etc. may be drawn and the procedure repeated. Points 2, 3 etc. are obtained as shown in Fig. 10.15(b). The 45° line, representing F
c = Fl/>' intersects the curve to give the factor of safety F
s for this trial circle.
