Figure P16.8 shows a smooth vertical wall retaining a sandy backfill underlain by clay. Assuming that the entire soil is in the active state, determine the magnitude and location of the resultant active force on the wall.

Figure P16.8

Sand y = 18.0 kN/m3 o' = 34°, c' = 0 4 m Clay 2 m 19.0 kN/m3 Ysat o' = 25°, c' = 5 kN/m?

Sand y = 18.0 kN/m3 o' = 34, c' = 0 4 m Clay 2 m 19.0 kN/m3 Ysat o' = 25, c' = 5 kN/m?
