The state plane stress in a mass of dense cohesionless sand is described by the following stresses:

Question:

Normal stress on horizontal plane = 296 kPa

Normal stress on vertical plane = 160 kPa

Shear stress on horizontal and vertical planes = +/- 64 KPa

Determine by means of the Mohr circle the magnitude and direction of the principal stresses. Is this state of stress safe against failure? (After A. Casagrande.)?
