Question

Importance of strength to weight ratio of materials

Answer 1

The strength-to-weight ratio of materials is called as the Specific Strength of the material.

This ratio value allows a person to compare materials of different masses or applications where resistance against breaking has priority. It is also a measure of the efficiency of a structure usually like bridges, etc.

The materials with the highest specific strengths are typically fibers such as carbon fiber, glass fiber, and various polymers, and these are frequently used to make composite materials.

These materials and others such as titanium, aluminum, magnesium and high strength steel alloys are widely used in aerospace, especially in making huge aircrafts like the Boeing 747 and 787 and other applications where weight savings are worth the higher material cost.

Answer 2

Well, the strength to weight ratio is also known as the specific strength .

This is used to known strength of a material hence high strength steel alloy  are normally used in the aerospace along with the other applications too.

Also, it is also helpful in making the composite material from the high specific strength material from material like carbon fiber. It is also widely used in the fiber a well as the textile applications. Tenacity is the word used in this regard in order to measure the specific strength
