A flat plate is floating above a 0.05-cm-thick film of oil and is being pulled to the right at a speed of 1m/s (see sketch for Problem 1.15). If the fluid viscosity is 0.4 N s/m², calculate the shear force τ on the lower and upper interfaces (e.g., on the floor and below the plate) and at the center of the liquid film.
