$(1.)$ A$.$

A large scale bearing capacity test on a footing of size $1\mathrm{.}05m1\mathrm{.}05m$ at a depth

of $1\mathrm{.}5$ m yielded an uitimate value of $141\mathrm{.}0$ kN $.$ Unconfined compression test on the soft saturated clay

yielded a strength of $0\mathrm{.}03\frac{N}{m}m{m}^2.$ If the unit weight of the soil is $1\mathrm{.}6\frac{g}{c}c,$ how much does the test value

differ from that obtained using Terzaghi's bearing capacib equation?
