4. The viscosity of incompressible viscous fluid is u = 0.96m Pa s. The
velocity field is given by:
vi = k(x² – x2); v2 = -2kx1x2;
V3 = 0|
where k =
s: At the point with coordinates (1,2, 1)m, for the plane with
normal in the direction of ê1:
(a) define the excess of the normal compressive force on top of the pressure p.
(b) determine the magnitude of the shear stresses.
