Young's modulus in Mechanical Engineering
(yʌŋz mɒdʒələs)
noun
(Mechanical engineering: Materials)
The Young's modulus is a measure of how stiff a bar of material is along its axis. It is equal to the stress applied divided by the resulting elastic strain.
This term is named for British scientist Thomas Young (1773-1829)
If the Young's modulus is large, the material will not shrink as much when it is compressed.
Young's modulus characterizes how difficult it is to stretch a substance in an elastic way.
