No, braces are not literally made out of train tracks, it's just the name given to the style.
Not really. They are made to move your jaw into place and minimise your overbite before you get train tracks.
Railroad tracks are made from steel.
The electromagnetic train is suspended above the rails thanks to the special metals that the tracks are made of. Just like a regular magnet, this causes the two masses to repel each other, and it makes the train suspend over the tracks.
Many toy train tracks are made out of wood, which is typically safe as long as they don't have sharp edges. Some are made with rubber, but they are less common. If you are referring to the electric train sets for kids (and adults), they use metal tracks that connect together and power the trains through its metal wheels. Non-electric toy trains may have wood, plastic, or rubber tracks.
I don't know if this is the main reason but, 'the tracks spread out the weight of the train so the wagons do not sink into the ground.'
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
Rails are made of iron and will rust over time if there is no rail traffic over the rails for an extended period of time. Rust is caused by oxygen and water and other components getting to metals that it reacts with. This applies to train tracks too.
Too much stain for anything else ... but 200 years ago wood ones were used.
Bmx tracks are made of mostly lime and gravel
No.
The average width of a road lane originates from a combination of safety standards, historical practices, and engineering guidelines. It is typically determined based on factors such as traffic volume, vehicle size, speed limits, and available space for roadway design. Standard lane width in the US is 12 feet, but can vary depending on the specific context or jurisdiction.
