The vertical stress increment (Ao) due to a point load acting on the surface of
linearly elastic medium is given as:
g = 4
n = 17
3P23
Ao =
27Vr? + z?
where P is the magnitude of the load, r is the lateral distance, and z is the depth of the
point where the stress is to be calculated. If P = 10g kN andr = 1.5 m, determine (by
using two methods: fixed-point and Newton-Raphson method) the depth z at which
the stress increment Ao = 10n kN/m?. (Take g=student group number A=1, B=2,
C=3, D=4, and E=5, n=student number in his/her group, and e =1x10-6)
