Young's Modulus

Written by Jerry Ratzlaff. Posted in Thermodynamics

Young's modulus measures the stiffness of an elastic material. It also can be called tensile modulus or elastic modulus.

Abbreviated as \(Yo\)

formula

\(E = \frac { \sigma } { \epsilon } \)

Where:

\(E\) = modulus of elasticity

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

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

Solve for:

\(\sigma = E \epsilon \)

\(\epsilon = \frac { \sigma } { E } \)
