A series of direct shear tests was performed on two types of soil. The recorded data of normal stress (o') and shear stress (t) for both the "Soil X" and "Soil Y" are given in the table below. Soil X Soil Y Normal stress, o Shear Stress, T (kN/m) 50 75 100 Shear Stress, t (kN/m) 40 50 60 Normal stress, o (kN/m) 50 75 100 (kN/m) 50 75 100 (i) Plot a graph between normal stress (o) and shear stress (t) for both the soils. (ii) Determine the shear strength parameters, i.e. friction angle (4) and cohesion (c) for both the soils.
