The 100-kg plate shown in Figure is resting on a very thin film of SAE 10W-30 oil, which has a viscosity of 0.0652 N.s/m². Determine the force P that must be applied to the center of the plate to slide it over the oil with a constant velocity of 0.2 m/s. Assume the oil thickness is 0.1 mm, and the velocity profile across the thickness is linear. The bottom of the plate has a contact area of 0.75 m² with the oil. Solution: 0.2 m/s P 30°
