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.
Not necessarily.
A short standard iron bar is a solid, straight metal rod typically made of iron or steel, with a standard length that is shorter than average for a standard iron bar. It is commonly used in construction, manufacturing, and other industrial applications for structural support or reinforcement.
The small bar magnet has a stronger magnetic field, at least at short distances.
liquid not solid or gas
When a juice bar melts, it changes from solid to liquid state, but the matter remains the same. The new form is still considered part of the liquid phase, with the same chemical composition as the solid juice bar.
No, electromagnets are stronger than bar magnets.
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.
Not necessarily.
yea it is, if its not a liquid than what is it??!
Tube Bar - album - was created in 1975.
Depends on the frequency. The higher the frequency the more the current has a tendency to stick to the surface. But for the most common frequencies cross-section area is more important for conductivity than solid or hollow.
Yes the density of a Hershey's bar is more than a three musketeers bar. The solid chocolate bar is more dense than the tasty nougat bar full of gas
Yes, because electromagnets can lose their magnetism.
Tube Bar Collector's Edition was created in 1975.
copper is one of the weakest metals. alloy is pretty strong almost like titanium
it is solid
No. The magnet has a sort of symmetry, in the sense that its two sides are "equal but opposite".
