(Viscosity) A Newtonian fluid having a specific gravity of 0.977 and a kinematic viscosity of 2.24 x 104 m2/s flows past a fixed surface. The velocity profile near the surface is shown in the figure below. Determine the magnitude and direction of the shearing stress developed on the plate. Express your answer in terms of U and ō, with U and ō expressed in units of meters per second and meters, respectively. U =sin() Fixed surface U i N/m² acting to right on plate
