Calculate the stress distribution with depth at a point 3.5 m from the corner (along the longest side) of a rectangular loaded area 15 by 35 m with a uniform load of 75 kPa.

qo = 75 kPa and z varies
Determine the stress increase using Fig. 10.4 (or Eq. 10.6) for the vertical stress under the corner of a uniformly loaded rectangular area. Use superposition as necessary. (Influence values presented below were determined using the Boussinesq solution as given by Eq. 10.6.)?

+(15, 38.5) 5.0 m. (0, 0) 15,0 m.
