Youngs modulusYoungs modulus 1AElastic modulus (Young's modulus), abbreviated as \(\lambda\) (Greek symbol lambda), also called modulus of elasticity, is the ratio of the stress applied to a body or substance to the resulting strain within the elastic limits.

Elastic Modulus formula

\(\large{ \lambda = \frac { \sigma } { \epsilon } }\)


\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus

\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain

\(\large{ \sigma }\)  (Greek symbol sigma) = stress

Solve for:

\(\large{ \epsilon = \frac { \sigma } { \lambda } }\)

\(\large{ \sigma = \lambda \; \epsilon }\)
