W U W h ↑ A block of weight W=21.6 N is being pulled over a table by another weight Wo= 29.8 N, as shown in the figure. The block bottom area A=38.7 cm² is in contact with the oil. Neglect the cord weight and the pulley friction. Assume a linear velocity profile in the oil film. What is the steady velocity U of the block if it slides on an oil film of thickness h= 1.66 cm and viscosity μ=8.959 kg/(m.s)? Your answer should be in m/s. Answer:

Step 1

8 N$. The area of the block in contact with the oil is $A = 38.7 cm^2 = 38.7 \times 10^{-4} m^2 = 0.00387 m^2$. The thickness of the oil film is $h = 1.66 cm = 1.66 \times 10^{-2} m = 0.0166 m$. The viscosity of the oil is $\mu = 8.959 kg/(m.s)$. Show more…
