(4) A soil profile is shown in the following figure. (a) Calculate the Over Consolidation Ratio at Point \( \mathrm{A} \) if the preconsilidation pressure is \( 1850 \mathrm{ps} \) (b) Specify if the clay layer is normally consolidated or overconsolidated. Unit weight of ware \( \left(\gamma_{w}\right) \) is equal to \( 62.4 \) pcf.
