Moist unit weight of soil, gamma \( =105 \mathrm{lb} / \mathrm{ft}^{3} \) Cohesion of soil, \( \mathrm{c}=400 \mathrm{lb} / \mathrm{ft}^{2} \) The factor of safety, \( F S=4 \) The internal friction angle of soil is 20 degrees A strip footing_is shown below. Using Terzaghi bearing capacity factors, determine the followings: 1. Ultimate bearing capacity, qu = \( \mathrm{lb} / \mathrm{ft}^{2} \) 2. Allowable bearing capacity, qa \( = \) \( \mathrm{Ib} / \mathrm{ft}^{2} \)
