disp("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.")
disp("Solution:")
t=u*du/dy*2*%pi/60*R*1000/100//shear stress in N/m^2
T=t*2*%pi*R*L*R/1000000//torque in Nm
P=T*du*2*%pi/60//Power in Watts
