cheapest material is Mild steel having very good properties of shaft.
Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft)/ 60 Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shâft3).
Most of the force in a shaft is carried by the outer layers of the shaft, and very. very little by the center. By using a hollow shaft you get almost the same turning strength for a lot less weight and material.
The Great Pyramid is made of limestone, and this is a common pyramid material.
The most common insulation material for HV use remains porcelain. Synthetic materials are fast replacing porcelain as the insulation material of choice.
Glass
Yeah, the best material simply pump shaft. I guess that pumping shaft's just the way it is
Styrofoam . . .
steel
I don't know if this is the cheapest, but they are recycled material and fair-trade: 24hourbracelets.com

The cheapest material available, normally cotton.
A steel head and a wood shaft.
automobile propeller shaft material
You cannot. The mass depends on the material of the shaft and that has not been specified.
It could be steel, brass, stainless or other corrosion resistant material
They hairs located at the base of the shaft are quite common.
Stainless Steel,Bronze,rubber,etc
