For supporting weight which is more strong a hollow shaft or a solid shaft?

A solid shaft is stronger compared with a hollow shaft. But this is only theoretical as some applications actually benefit from the use of hollow shafts. If the system is required to accelerate or decelerate then a hollow shaft is more desireable as although the overall diameter is increase, it is possible to make a stronger shaft with less material, therefore less weight and inertia. Also worth bearing in mind that a hollow shaft is torsionally more flexible and more likely to flex and absorb uneven loads on the system, such as any kick 'when' accelerating or decelerating the system.

a solid shaft is stronger. however the majority of the load is handled by the exterior of the shaft. shafts are made hollow to save weight and improve economy. more shafts can be made from the same amount of material. LEss weight on a cars driveshaft adds up to less gasoline consumed. this gas savings is porbably not significant to the owner of a single car but everycar in the world not hauling around an extra pound or two saves a large amount of gasoline.
from an design perspective usually the choice is not between hollow or solid in the same diameter. In real life, the solid shaft has a lesser diameter than the hollow shaft,

For sure the solid shaft is the stronger.
because it has a larger cross section area, which means more capability to support weight.
the stress on a shaft is given by this formula:
segma= P/A
P is the applied force
A is the surface area of the croos section
as you noticed in the above formula, the bigger is the area the smaller is the stress , for a given force.
so for a hollow shaft and solid shaft of the same dia, the solid is more strong, because he s able to support bigger force.

The solid shaft is stronger. If you were to have a hollow shaft with the same cross sectional area as the solid shaft then the hollow shaft would be stronger but then the outer diametr would be larger.

solid of course more surface area to distribute the weight resulting in less weight per sq. inch to support.
