What Are Principal Stresses And Principal Planes?

What Are Principal Stresses And Principal Planes? Principal stresses are maximum and minimum value of normal stresses on a plane (when rotated through an angle) on which there is no shear stress. Principal Plane. It is that plane on which the principal stresses act and shear stress is zero. What are plane stress and principal

Does Laminar Or Turbulent Flow Have More Shear Stress?

Does Laminar Or Turbulent Flow Have More Shear Stress? Does laminar or turbulent flow have more shear stress? The figure below compares a typical laminar layer with an averaged turbulent layer. . This means that because of the greater velocity gradient at the wall the frictional shear stress in a turbulent boundary is greater than
