Extracted text: A soil element is shown in Fig. 1. Determine the following (clearly show calculation procedures): Normal and shear stress on plane EF Use rotation method to locate the normal and shear stress on the plane EF (plot the Mohr's circle by compass and locate normal and shear stress in ) 0, = 45 kN/m? = 40 kN/m2 ху F 0, =150 kN/m? = 40 kN/m? 22° ху E A В
