Yes it is a one piece shaft.
Depends on what you mean by "better". For the same dimensions, a solid shaft will be a bit stronger, but also a lot heavier. If you were to make a hollow shaft of the same weight, but a bigger diameter, it'd be a lot stronger than the solid shaft.
Weight savings.
A ball valve is a ball with a hole through it that rotates around its axis to expose the hole for flow or the solid wall of the ball for no flow. The butterfly valve is a flat piece that is supported in the middle by a shaft that opens or closes when the shaft is rotated.
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).
The formula for calculating weight of a solid shaft is dia x dia x length x 7.8 x 1000000. This formula is the most commonly used.
The large piece of the solid part of the earth is called a tectonic plate
yes
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.
Yes it is a solid because if a piece of cheese is a solid then why is a block of cheese is not is the same thing
If, by 'one piece', you mean solid -as opposed to laminated- then the answer is that a solid core will have significantly-higher eddy current (circulating current) losses than a solid core.
The size of a nanoparticle is smaller than any one piece of a solid; also an ion is smaller than a nanoparticle.
