A hydraulic lift of the type commonly used for greasing automobiles consists of a 280.18 mm cylinder. The annular space between the ram and cylinder is filled with oil having a kinematic viscosity of 0.00042 m2/s and specific gravity of 0.86. If the rate of travel of the ram is 0.22 m/s, find the frictional resistance when 2m of the ram is engaged in the cylinder.
