Marks: +1, -0

2 {m} × 4 {m}

rectangular footing has to carry a uniformly distributed load of

120 {kPa}

. As per the

2: 1

dispersion method of stress distribution, the increment in vertical stress (in

{kPa}

) at a depth of

2 {m}

below the footing is

Solution:

Increment in the vertical stress

=\;{120 × 2 × 4}/{(2+h)(4+h)}

=\;{120 × 2 × 4}/{(2+2)(4+2)}=40 {kPa}
