A 0.30 m x 0.30 m concrete pile 20 m long is driven in a clayey soil having an unconfined compressive strength of 110 kN/m². The unit weight of the clayey soil is 18 kN/m³. Frictional constant is 0.76 due to skin friction. Assume a factor of safety equal to 2.0 and a bearing capacity factor N_c = 9.
Compute the capacity of the pile due to skin friction only.
