A retaining wall 5 m high is supporting horizontal backfill having a dry unit weight of 15.70 kN/m^3. The cohesionless soil has an angle of internal friction of 32 degrees. Compute the Rankine active force on the wall if the water table is located at a depth of 2.5 m below the ground surface. The saturated unit weight is 18.7 kN/m^3.
