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.

What precautions should you take to prevent injuries when dealing with heavy loads?

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
