6. A hydraulic lift (see below) of the type commonly used for greasing automobiles consists of a
280.00 mm diameter ram which slides in a 280.18 mm-diameter cylinder, the annular space
being filled with oil film of thickness t = 0.09 mm, having a viscosity 0.3612 kg/(m s). If the
rate of travel of the ram is v= 0.22 m/s, find the frictional resistance when 2 m of the ram is
engaged in the cylinder. Take the weight of ram as 500 N.
