Calculate the dynamic viscosity of an oil, which is used for lubrication between square plate of size 700 mm x 700 mm and inclined plane with an angle of inclination 45° as shown in Fig. below. The weight of the square plate is 250 N and it slides down the inclined plane with a uniform velocity of 0.35 m/s. The thickness of oil film is 1.4 mm. Liquid film of thickness h 250 sin 25 u = 0.35 m- 250 cos 25 - Block contact W-250N area A
