+ A lubricated shaft rotates inside a concentric sleeve bearing at 1200rpm,the clearance is smaal with respect to the radius and hence a linear distribution velocity
+ distribution may be assumed.What are the power requirements to rotate the shaft?R=2cm , L=6cm , dy=0.1mm , and u=0.2N.s/m^2.
+
+ Solution:
+
+ Power required to rotate the shaft =
+
+ 95.251282
