A 12 m³ moist soil sample with volume of soil solid as 9m³ is examined and the laboratory results reveal that the porosity of the soil sample is 25 %. The relative porosity of the sample is _____ .

A steel column pinned at both ends has a buckling load of 160 kN. If the column is effectively held in position and restrained against rotation at one end but neither held in position nor restrained against rotation at the other end, then its buckling load will be ________ kN.

A strip footing of 2m width is located at a depth of 2.0m in a stiff clay of saturated unit weight 21 kN/m³ and Φ_u = 0. For a factor of safety of 3 with respect to shear failure, what load (in kN/m) could be carried by the footing per unit length? Use Terzaghi bearing capacity equation [value of c_u for purely cohesive soil = 120 kN/m²]
