A 3-in.-diameter shaft is supported by a bearing 3 in. in length with a diametral clearanceof 0.004 in. It is lubricated by oil that at operating temperature has a viscosity

of 5 µreyn.The shaft rotates at 1800 rpm and carries a radial load of 1200 lb. Estimate the bearingcoefficient of friction and the power loss using the Petroff approach.
