Solution:

Determine the width of strip footing to carry a load of 750 kN/m at a depth of 1.6 m in a c-φ soil having unit weight of 18 kN/m³ and c = 20 kN/m², φ = 25°. Take FOS = 3 and assume general shear failure.

Solution:

Find the water content of the soil, if the weight of the container is 50 g and the weight of the container and wet soil sample is 100 g. On oven drying for 24 hours, the weight of the container with dry soil is found to be 75 g.
