Figure P17.1 shows a gravity retaining wall retaining a granular(c‘=0) backfill. The same soil is present at the bottom of the wall and on the left. The unit weight and the friction angle of the backfill are 18.5 kN/m^3 and 35 degrees, respectively. The unit weight of the concrete is 24 kN/m^3 and delta’=(2/3)phi’ where phi=35 degrees. Determine the factors of safety with respect to overturning, sliding, and bearing capacity failure.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
