g Assume that both a triaxial shear test and a direct shear test are to be performed on a sample of dry sand. When the triaxial shear test is performed, the specimen fails when the major and minor principal stresses are 80 and 20 lb>in.2 , respectively. When the direct shear test is performed, what shear strength can be expected if the normal stress is 4000 lb>ft2

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.
