For the design of a shallow foundation, given the following: c^{\prime}=72 \mathrm{kN} / \mathrm{m}^{2} \text { Unit weight, } \gamma=17 \mathrm{kN} / \mathrm{m}^{3} Modulus of elasticity, E, = 1400 kN/m-%3D

\text { Poisson's ratio, } \mu_{s}=0.35 Foundation:L= 2 m B = 1 m D, = 1 m Calculate the ultimate bearing capacity. Use Eq. (6.42). \phi^{\prime}=20^{\circ}
