By stronger, we need to define the loading conditions of the rod or pipe. The strength of a rod or pipe is typically evaluated with axial, transverse (bending), and torsion loads. With the same diameter and the same material, a solid rod is stronger than a hollow pipe. However, with the same weight and material, the hollow pipe is stronger than a solid rod. Because a hollow pipe is lighter than a solid rod at the same diameter, the hollow pipe would have a larger diameter in order to match weights with the solid rod and a larger diameter rod or pipe is stronger than a smaller diameter one.
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.
For a given outer diameter, the solid shaft is stronger, but it weighs more.For a given weight, the hollow shaft is stronger because it has a bigger diameter.due to less weight & less bending moment..............the resultant bending moment for a solid pipe is much larger than for a hollow one because of their weight difference
Not usually, but it depends on the direction of stress involved.
hollow bones are stronger than compact bones
if they are short or in tension they are the same, when they bend the hollow tube has a bigger second moment of area and so is stronger to any bending moment
A solid ball rolls faster than a hollow ball.
yes
In general, a tube is stronger than a solid bar when subject to torsional loads, because the material is distributed away from the center axis. However, a solid bar is usually stronger than a tube when subjected to bending loads, because it does not have hollow sections where stress concentration can occur. The specific strength comparison between a tube and a solid bar depends on their dimensions, material properties, and the type of load applied.
yes
Chicken bones are not stronger than the human bones because they are hollow.
Solid doors are generally more durable than hollow doors because they are made of a solid piece of material, such as wood or metal, which makes them stronger and less prone to damage. In terms of sound insulation, solid doors are also more effective at blocking out noise compared to hollow doors, which have empty spaces inside that allow sound to pass through more easily.
