What material would be the best choice for the support beams of a building Kevlar a thermoset steel wood?
The best choice for this question would be B. Steel.
Which of the following materials is the best choice for an insulating material?
Answer Expert Verified. You are correct, the answer is C. Good insulators are materials that do not allow heat, electricity, light or sound pass through easily. Materials like steel and silver (which are metals) are not good insulators because they make good conductors.
What does the word polymer mean quizlet?
polymer. Describes a substance that has been made artificially through chemical synthesis (doesn’t come from a natural source) Synthetic.
How expensive is a superconductor?
Superconducting cable used to cost around $1,500 per kiloamp per metre, the standard industry measure of conducting capacity. Now, American Superconductor sells wire for $200 per kiloamp per metre, and expects to reduce the cost to about $50 per kiloamp per metre when it opens a new production plant next year.
Why are superconductors so expensive?
The temperature thresholds are incredibly low, and thus incredibly expensive to maintain. More complex materials, some of which can achieve superconductivity above cryogenic temperatures, are decidedly within the realm of quantum weirdness, and have to do with transient interactions between electron pairs.
How do you make a superconductor?
To make an yttrium-barium-copper-oxide superconductor, you will need:
- Yttrium Oxide.
- Barium Carbonate (TOXIC)
- Cupric Oxide.
- A Laboratory Furnace or a converted pottery kiln.
- Labware made of alumina.
- An Oxygen Source.
- Liquid Nitrogen and a rare-earth magnet for testing and demonstrating the superconductors.
How much weight can a superconductor hold?
It is about superconductivity and quantum levitation. It tells that super-thin, three-inch disk can levitate something 70,000 times its own weight. In exact terms, presentation @9:40 says: 3mm thick disk could carry 1000kg small car.
Where do we use superconductors?
Low-temperature superconductivity
- Magnetic Resonance Imaging (MRI) and Nuclear Magnetic Resonance (NMR)
- Particle accelerators and magnetic fusion devices.
- HTS-based systems.
- Electric power transmission.
- Magnesium diboride.
- Trapped field magnets.
