Question:

A hydraulic lift in a service station has a \(32.50-\mathrm{cm}\)-diameter ram that slides in a \(32.52-\mathrm{cm}\)-diameter cylinder. The annular space is filled with SAE 10 oil at \(20^{\circ} \mathrm{C}\). The ram is traveling upward at the rate of \(0.10 \mathrm{~m} / \mathrm{s}\). Find the frictional force when \(3.0 \mathrm{~m}\) of the ram is engaged in the cylinder.
