(c) The following results were obtained from a direct shear test on a sandy clay sample. Normal Load (N) 360 720 1080 1440 Shear Load Proving Ring Reading (Divisions) 13 19 26 26 If the shear box is 60 x 60 mm² and the one proving ring division is equals to 20 N, estimate the shear strength parameters of the soil drawing a graph. Would failure occur on a plane within this soil at a point where the normal stress is 320 kNm2 and the corresponding shear stress is 138 kNm ²?
