Question

The Young's modulus values for iron and lead are 210 GPa and 16 GPa, respectively. Based on the information, which statement is true for the two
metals?

A. Lead is more ductile than iron.

B. Iron is more ductile than lead.

C. Iron is softer than lead.

D. Lead is a better conductor than iron.

Answer 1

Lead is more ductile than iron. The correct option is A. Lead is more ductile than iron

Young's modulus

From the question, we are to determine the statement which is true

First, we will define the term Young's modulus

Young's modulus is a measure of the stiffness of an elastic material. It is also given as the ratio of stress to strain. That is,

$Young's\ modulus = \frac{Tensile\ stress}{Tensile\ strain}$

The greater the modulus, the stiffer the material.

Materials with low Young's modulus tend to be ductile and materials with high Young's modulus tend to be brittle

Since the Young's modulus value for iron is higher than that of lead, then iron is stiffer than lead.

Thus, lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
