A rectangular footing of size 3 m × 2 m exerts a pressure of 100 kN/m2 on a cohesive soil whose Young's modulus is 5 × 104 kN/m2 and mu is 0.5. What is the immediate settlement at the centre for flexible footing? Assume that for an \(\rm\frac{L}{B}\) ratio of 1.5, shape factor (I) = 1.36 for flexible footing at centre.
