The general definition of elastic modulus is
\(\frac{stress}{strain}\)
\(\frac{strain}{stress}\)
\(stress \times strain\)
\(\sqrt{\frac{stress}{strain}}\)

Elastic modulus is the ratio of pressure (stress) applied to a body to the resistance (strain) produced by the body.
= \(\frac{stress}{strain}\)
