What is stronger hollow pipe or solid pipe?

Question

Smoking pipes are available in a variety of materials and styles. Briar pipe pipes are the most common kind of smoking pipe and have a classic appearance. The wood is absorbent and flame-resistant, which makes it suitable for briar pipes. There are many forms and sizes that briar pipes can take. In addition to briar, smoking pipes can also be made from other materials.
Besides the material, the shape of the pipe is also important. There are many classic tobacco pipe shapes. Many pipe makers and smokers disagree on the names of some pipes. Most traditional shapes can be straight or bent, with varying proportions, different stem configurations, and different capacities.
Common Smoking Pipe Styles
Billiard: The Billiard is the most popular and well-known shape, perfect for those approaching slow smoking. Its design is based on the balance and proportion between mouthpiece and shank. The cylindrical shape of the head means that the temperature remains constant, which makes this shape very practical and versatile.
Bent: This is the bent tobacco pipe by definition, from which many variations are derived. The advantage of the Bent is in the balance on the teeth.
Apple: Named for its resemblance to the fruit, the Apple style gained popularity.
Pot: The thicker walls of Pot pipes provide better insulation, though they may be heavier than straight pipes.
Prince: Named after a Duke, the Prince style emerged. It has a wide, round bowl and is available in small, medium, and large sizes, typically with a slightly bent mouthpiece.
Dublin: This is perhaps the oldest style, shaped like a cone with varying slopes.
Bulldog: Named for its rugged appearance, the Bulldog is an outdoor style distinguished by its diamond-shaped bowl and shank, often with grooves.
Rhodesian: The shank is round, compared to the square shank found on the Bulldog. The top of the bowl differs as well, with a more rounded and smaller tapered rim.
Poker: The Poker shape is two cylinders at 90 degree angles to each other, the larger for the bowl and the thinner for the shank.
Zulu: The Zulu is a little more than a curved Dublin, the bowl is angled a little more, while being set off beautifully by the curved mouthpiece.
