Homework Statement
The conical bearing is placed in a lubricating Newtonian fluid having a viscosity μ.
Determine the torque T required to rotate the bearing with a constant angular velocity of ω. Assume the velocity profile along the thickness t of the fluid is linear.
Homework Equations
v=ωr
τ=μ(dy/dt)
