A sealed journal bearing is formed from concentric cylinders. the inner and outer radii are 25 and 26 mm, the journal length is100 mm, and it turns at 2800 rpm. The gap is filled with oilin laminar motion. The velocity profile is linear across thegap. The torque needed to turn the journal is 0.2 N*m. Calculate the viscosity of the oil. Will the torque increaseor decrease with time? Why?
