An overhead water tank is supported at a depth of 3m by four isolated square footing of sides
2m each placed in a square pattern with a centre to centre spacing of 8m. Compute the
vertical stress at the foundation level (i) at the centre of the four footings and (ii) at the centre
of one footing. Adopt Boussinseq's point load approximation. The load on each footing is
750kN.
