Question 2 A hydraulic lift as shown in the figure below consists of a 50 cm diameter ram and slides in a cylinder of diameter 50.015 cm. Oil having kinematic viscosity of 0.025 cm³/s and 0.85 specific gravity fills the annular space. If the rate of travel of the ram is 9.15 m/min, find the frictional resistance when 3.85 m of ram is engaged within the cylinder, stating clearly any assumptions. Question 3 fs: Ts.
