Question: A hydraulic lift of the type commonly used for greasing automobiles consists of a 10,000 in diameter ram that slides in a 10,006 in diameter cylinder (as shown in the attachment), the annular space being filled with oil has a kinematic viscosity of 0.0038 ft^2/sec and a specific gravity of 0.83. If the rate of travel of the ram v is 0.5 fps, find the frictional resistance, F is when 6 ft of ram is engaged in the cylinder.

Solution:
Because the diameter of the ram D = 10000 in = 10000/12 ft
Length of ram L = 6 ft
Therefore surface area of the ram in contact with cylinder
A = ...
