Conical friction clutches
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25. The angle of the cone being 50o. Find the greatest power that will be transmitted at 1200rpm together with the least axial load required without slipping. The permissible pressure between the surfaces is not to exceed 0.9bar.
