Figure 17.26 shows a continuous foundation with a width of 1.8 m constructed at a depth of 1.2 m in a granular soil. The footing is subjected to an eccentrically inclined loading with e = 0.3 m and α = 10°. Determine the gross ultimate load, Q_u(ei), that the footing can support using the following.
a. Meyerhof (1963) method [Eq. (17.58)]. Use Table 17.2 and Eqs. (17.32) through (17.42).

b. Saran and Agarwal (1991) method [Eq. (17.59)].

c. Patra, et al. (2012) reduction factor method [Eq. (17.60)]. Use Table 17.2 and Eqs. (17.32) through (17.42).
