Hello, how would you solve the following question?
a 10cm diameter shaft moving inside a 22cm long sleeve. The sleeve is covered with a 0.01cm thin film of oil. The force required to move the shaft at 0.15 m/s is 12 N.
i) Assuming a linear velocity variation, what is the velocity gradient in the oil?
ii) What is the shear stress on the shaft?
Thanks! please show your workings HELP!
