Under the corner at point C Under the center D. If another footing of size 3 x 1 m with a total load of 450 kN is constructed adjoining the previous footing, what is the additional stress at point C at the same depth due to the construction of the second footing? Using Newmark's chart, determine the vertical stress due two both footings at a depth of 2.5 m under point E.
