Question \( 6(25 \%) \) A retaining wall is to be constructed in a clayey sand deposit as shown in the figure below. Consider water pressures acting behind and in front of the wall. Consider the depth of the tension crack. Calculate and sketch the active and passive earth pressure distributions using Rankine earth pressure theory and check if this wall is safe considering horizontal force equilibrium condition (i.e., Resisting forces \( > \) Disturbing forces).
