Are elastic materials always ductile? Explain your answer.
What will be an ideal response?
Ductility and elasticity are closely related. Ductility is a measure of how much a material will yield before breaking. Metals such as copper and brass can be stretched (drawn) into wires because they are ductile.
Elasticity is the ability a material has to stretch under load but return to its original shape and length. Therefore, elastic materials are always ductile.
