JordanJavelins are made of materials like steel, aluminum, and carbon fiber because these materials are strong, lightweight, and offer good flexibility. Steel is durable but heavier, aluminum is lightweight but less durable, and carbon fiber is a combination of strength and lightness, making them suitable for throwing long distances in Track and Field competitions.

What are the materials used to make a javelin?
Javelins are typically made from materials such as carbon fiber, aluminum, or a combination of both. The shaft is usually lightweight and rigid to allow for optimal throwing distance and accuracy. The tip of the javelin is typically made of metal such as steel or a hardened aluminum alloy for piercing the ground upon landing.
What are some common thermal conductors?
Common thermal conductors include metals such as copper, aluminum, and stainless steel. Other materials like graphite, carbon steel, and some ceramics also exhibit good thermal conductivity properties.
What two materials are the best to withstand tension?
Two materials known for their high tensile strength are steel and carbon fiber. Steel is a strong and reliable material commonly used in construction and engineering applications. Carbon fiber is lightweight yet incredibly strong, making it ideal for aerospace, automotive, and sporting applications where weight reduction is crucial.
What if your race car weighs 1.5 tons. To make the car faster you replaced the steel body with carbon-fiber and reduced the weight by 300 pounds. How much does your race car weigh now?
After replacing the steel body with carbon-fiber and reducing the weight by 300 pounds, the race car now weighs 1.35 tons (or 2,700 pounds).
How light is carbon fiber?
Carbon fiber is a lightweight material that is five times lighter than steel, yet it is also very strong. Its low weight and high strength make it a popular choice for applications where reducing weight is important, such as in aerospace, automotive, and sports equipment.
