Refer to the 15-m-high wall shown in the figure. Assume that the retaining wall shown in figure can yield sufficiently to develop an active state (i.e., before the tensile crack occurs).< (a) Determine the Rankine active force per unit length of the wall.< (b) Determine the location of the resultant line of action. Assume, Y 10 kN/m³< = 3 m 1 m 5 m 4 m 2 m P₁ = 35º 9₂ = 32° 0 P4 = 100 Φϛ΄ = 200 Y₁ = 17 kN/m³ Y sat2 = 19 kN/m³ Y sat3 19.5 kN/m³ C₂ = 25 kPa Y sat4 18 kN/m³ C4 = 30 kPa Y sat5= 18 kN/m³ C5 = 20 kPa Groundwater table Refer to the 15-m-high wall shown in the figure.
