Optimized shape of the VR Tapered bucket changes the material distribution. This results in a forward shift of the combined bucket and material during filling, thus, faster filling characteristics.

Calculates the load distribution in a tapered roller bearing under combined loads, and analyzes the effect of misalignment on the loads in a tapered roller and raceways.

In addition, the problem about effects of arterial tapered Angle on the velocity distribution of blood flow in an artery is also dis cussed.
