Questions and Answers

What is the value of Young's modulus (Y) for copper?

Young's modulus for copper is $Y = 11.7 \times 10^{10} \text{ N/m}^2$.

What is the value of Poisson's ratio ($\sigma$) for copper?

Poisson's ratio for copper is $\sigma = 0.3$.

How do you calculate the rigidity (shear modulus, G) of copper using Young's modulus and Poisson's ratio?

The rigidity of copper can be calculated using the formula $G = \frac{Y}{2(1 + \sigma)}$, where $Y$ is Young's modulus and $\sigma$ is Poisson's ratio.

What is the formula for calculating rigidity?

The rigidity (G) of a material is calculated using the formula G = Y / (2 * (1 + sigma)), where Y is the Young's modulus and sigma is the Poisson's ratio.
