A 6.3 m high retaining wall supports a 4.5 m soil backfill having a cohesion of 25 kPa and an angle of internal friction of 30 ̊. The soil backfill was subjected to a laboratory test it was found out that it has a moist volume of 0.01055 m3, a moist weight of 0.1935 kN. After oven drying, it has a weight of 0.1668 kN and from analysis it has a combined volume of air and water of 0.004477479 m3. If the water is 5.2 m high.

Determine the following:

a.Active Force Before Tensile Crack.

b.Active Force After Tensile Crack.

c.Passive Earth Force.
