2.
The state plane stress in a mass of dense cohesionless sand (c=0) is described by the following stresses:
Normal stress on horizontal plane = 300 kPa
Normal stress on vertical plane = 100 kPa
Shear stress on horizontal and vertical planes = ± 50 kPa
Determine by means of the Mohr circle the magnitude and direction of the principal stresses. Is
this state of stress safe against failure assuming φ= 20o?

- In a zone with a constant stress gradient of a mechanical- structural element, the stresses acting in the "x" direction are Ox = 5900 psi and Txy = 1950 psi. Determine the allowable values if the maximum shear stress is limited to Tmax = 2500 psi. for Tyarrow_forwardAn oil of viscosity 1.5 Ns/m² flows between two parallel plates and the maximum velocity of flow is 1.5 m/s. If the shear stress acting at plate is 105 N/m², then the distance between the plates is mm (round off to two decimal places).arrow_forwardAt a location where the ground surface is horizontal, the vertical stress at one point in the underlying soil deposit is 190 kPa and the horizontal stress is 76 kPa. If these stresses represent principal stresses, what is the maximum shear stress passing through the point? What is the value of the normal stress on the plane of maximum shear?arrow_forward
