A 10 cm conical pointed shaft turns in a stationary conical bearing with an angular velocity of 5 rad/s. An oil of viscosity 0.036 N.s/m² fills a 2 mm gap between the shaft and the bearing. Find the shear stress acting on the surface of the conical shaft. Also, calculate the viscous torque on the shaft.
