A 2.0 m wide continuous foundation is placed at 1.5 m depth in a saturated clay where cu 40 kN/m2 and y 18.5 kN/m2. At 2.0 m below the ground level, this clay layer is underlain by a stiffer clay where c-60 kN/m2 and y 19.0 kN/m3 What would be the maximum wall load allowed with FS 3?

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
