The block of mass m shown in the picture is to be moved at a constant velocity of V up the smooth inclined surface of angle 0. Draw the free body diagram of the block and determine the force F required to be applied along the incline if the gap between the block and the surface measures b and contains SAE oil of absolute viscosity . Assume that the velocity distribution in the gap is linear and the area of the block in contact with the oil is A. The acceleration due to gravity is g. Express your answer in terms of the variables provided in the problem. F M
