In the landing gear for the Airbus 320 , engineers wish to design a damper (a device for reducing vibrations). 1.6m3 of liquid lubricant which has weight 13342N is injected between two parallel plates with 20cm distance in the damper device being tested. The top plate moves 12m in 2.5 seconds. If the kinematic viscosity of the liquid is 43.2cSt, calculate the shear stress which has occurred during this movement
