Numerical analysis
G=5
N=35

Transcribed Image Text:The vertical stress increment (Ao) due to a point load acting on the surface of
linearly elastic medium is given as:
3P23
Ao =
27Vr² +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 and r = 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/m². (Take g=
n=student number
and ɛ =1x10-6)
