Pls. solve clearly in handwriten. Thank you
![. According to the elastic theory, the vertical stress induced by a flexible line
load length has an intensity of "q" units/length on the surface of a semi-
infinite soil mass, this can be estimated by the expression:
Ap = 0.637 q/N
where:
N = z[1+)]
r = horizontal distance of the point from the line load
z = depth of the point at which stress is induced
A masonry wall weighing 9 kN per lineal meter is carried by a wall footing
0.60 m wide.
a) Evaluate the bearing pressure exerted by the footing onto the
supporting soil
