Problem:
An auto lift consists of a 35.56-cm diameter ram which slides in a 35.58-cm diameter cylinder. The annular region is filled with oil having a kinematic viscosity of 0.00037 m2/s and a specific gravity of 0.85.
Required:
Question: If the rate of travel of the ram is 0.15 m/s, estimate the frictional resistance when 2.44 m of the ram is engaged in the cylinder.
Note: Provide thorough explanation of every question given in the problem.
