For a parallel plate arrangement of the type shown in the figure below it is found that when the distance between plates is 2 mm, a shearing stress of 172 Pa develops at the upper plate when it is pulled at a velocity of 1 m/s. Determine the viscosity of the fluid between the plates. Express your answer in SI units.

The uniform 8-ft board is pushed down into the water so it makes an angle of 30 degrees with the water surface. The cross section of the board measures 3 inch by 9 inch and its specific weight is 30lb/ft.3. Determine the Vertical Force F needed to hold its end in this position. A) None of the above B 66.564 Ib C) 19.90 Ib (D) 5.55 lb
