# Modulus of Elasticity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Modulus of elasticity (also known as modulus elasticity) is the ratio of the stress applied to a body or substance to the resulting strain within the elastic limits.

## formula

$$\lambda = \frac { \sigma } { \epsilon }$$

Where:

$$\lambda$$ (Greek symbol lambda) = modulus of elasticity

$$\sigma$$ (Greek symbol sigma) = stress

$$\epsilon$$ (Greek symbol epsilon) = strain

Solve for:

$$\sigma = \lambda \epsilon$$

$$\epsilon = \frac { \sigma } { \lambda }$$
