4. A large movable plate is located between two large fixed plates as shown in the figure below. Two Newtonian fluids having the viscosities indicated are contained between the plates. Determine the magnitude and direction of the shearing stresses that act on the fixed walls when the moving plate has a velocity of $$5.86\mathrm{m}/\mathrm{s}$$ as shown. Assume that the velocity distribution between the plates is linear.
