1) The following results were obtained from a shear box test carried out on a set of soil samples. The apparatus made use of a proving ring to measure the shear forces. Normal load (kN) Strain (%) 10 0.2 0.4 Proving ring dial gauge readings (no. of divisions) 8.5 16.0 22.5 27.5 31.3 33.4 33.4 33.4 16.5 27.0 34.9 39.9 0.6 45.0 46.0 47.6 47.6 47.6 28.0 39.0 46.8 52.3 56.6 59.7 61.7 62.7 62.7 62.7 The cross-sectional area of the box was 3600 mm² and one division of the proving ring dial gauge equalled 0.01 mm. The calibration of the proving ring was 0.01 mm deflection equalled 8.4 N. Determine the strength parameters of the soil.
