A class demonstration showed that lift is present when a cylinder rotates in an air stream. A string wrapped around a paper cylinder and pulled causes the cylinder to spin and move forward simultaneously. Assume a cylinder of \(5 \mathrm{~cm}\) diameter and \(30 \mathrm{~cm}\) length is given a rotational speed of \(240 \mathrm{rpm}\) and a forward speed of \(1.5 \mathrm{~m} / \mathrm{s}\). Estimate the approximate lift force that acts on the cylinder.
