Question

Which material has the highest Young's modulus?

Answer 1

1. The hardest substance is diamond. Its Young's modulus is the largest.
2. The ratio of longitudinal stress to longitudinal strain is known as Young's modulus.
3. Young's modulus is mathematically expressed as: $E=\frac{\sigma }{\epsilon }$
4. Where, $\sigma$ is stress, $\epsilon$ is strain.
