Adirect shear test was performed on a specimen of dry sand. the specimen was 50 mm by 50 mm square and 25 mm thick (height). a normal stress of 192 kpa was applied to the specimen and the shear stress at failure () was 120 kpa.
a. what is the effective friction angle of the sand?
b. for a normal stress of 200 kpa, what shear force (f) will be required to cause failure of the specimen? (report answer in n).

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

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
