1. The problem statement, all variables and given/known data 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. 2. Relevant equations v=ωr τ=μ(dy/dt) 3. The attempt at a solution So our professor was in the middle of a problem like this before running out of time and abandoning it . . . so I'm not really sure where to start. I know trig is used to find a relationship between R and H, but setting up the integral and actually integrating . . . I'm lost . . .
