A rectangular flexible footing of size 3 m × 2 m exerts a uniform pressure of 100 kN/m2 on a cohesive soil. If Young's modulus of the soil is 5 × 104 kN/m2 and Poisson's ratio is 0.5, what is the immediate settlement at the center of the footing? (Take shape factor I = 1.36 for L/B = 1.5)

A Standard Penetration Test (SPT) is conducted in fine sand below the water table, and the observed blow count (N) is 25. Applying Terzaghi and Peck's dilatancy correction for saturated fine sand when N > 15, what is the corrected value of N?

When conducting a CBR test, the load dial reading at 2.5 mm penetration is observed to be 33 divisions. If one division represents a 190 kg load on the calibration chart, and the standard load for 2.5 mm penetration is 1370 kg, what is the CBR value at 2.5 mm penetration?
