А Solid cone of radius so and vertex
ongle 2thitha
is to rotate at an angular
velocity w. An ail of viscosity
and thikness h' fills the
gap
between the Cone and having
Determine the torque T required
to rotate the cone ?
​

Answer 1

Answer:

The elementary ring of bearing surface of its radius is r + dr and height is h + dh.is taken at a distance h from the apex. A solid cone of radius R and vortex angle

An oil of dynamic viscosity and thickness t fills the gap between the cone and the housing.
