Refer to Figure 5.25. For a foundation on a layer of sand, given: B?= 5 ft, L?= 10 ft, d?= 5 ft,? = 26.6?, e?= 0.5 ft, and ? = 10⁹. The Pressuremeter testing at the site produced a mean Pressuremeter curve for which the p_p(m)?versus ?R/R_o?points are as follow:

What should be the magnitude of Q_o?for a settlement (center) of 1 in.?
