Problem $2$:

A circular vertical load with a radius of $(r)4$ meters is applied to a clay layer. The load is $q=100$

$k\frac{N}{m^2}.$ Young's undrained $("$short$-$term"$)$ modulus is $E_u=10$MPa

Using this data, the following must be done:

Calculate the increase in stress due to the application of the load at points in the center of

the load at $2\mathrm{.}0$ and $4\mathrm{.}0$ meters in depth from the surface.

Calculate the undrained $("$short term"$)$ surface settlement in the center of the load.
