Redo Problem 1 with γ = 18 kN/m3, ϕʹ = 40̊, cʹ = 0, and the center-to-center strut spacing in the plan = 4 m.

Problem 1

Refer to the braced cut shown in Figure 1. Given: γ = 17 kN/m3, ϕʹ = 35̊, and cʹ = 0. The struts are located at 3 m center-to-center in the plan. Draw the earth-pressure envelope and determine the strut loads at levels A, B, and C.
