A block of weight W is being pulled over a table by another weight Wo, as shown in Fig. P1.55. Find an algebraic formula for the steady velocity U of the block if it slides on an oil film of thickness h and viscosity ?. The block bottom area A is in contact with the oil. Neglect the cord weight and the pulley friction. U W Wo
Solve the same problem assuming non-linear velocity distribution of the form v = Uy/h - y²/h²
