When shear stresses are present in a fluid, the pressure at a point is:

When shear stresses are present in a fluid, the pressure at a point is: Correct Answer Not equal in all directions

Concept:

Pascal’s principle: 

  • Pascal’s Law is the principle of transmission of fluid pressure.
  • It says that "a pressure exerted anywhere in a point of the confined fluid is transmitted equally in all directions throughout the fluid”.

  • When fluid is in the flowing state the pressure is also influenced by the viscous effect of the liquid.
  • if fluid is viscous and moving then both the conditions of being ideal and static is not maintained by the fluid and hence pressure at a point in a fluid is not the same in all directions.
  • So, If shear stresses in liquid then pressure at a point in a fluid is not equal in all directions.

Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?
