Question: If a material has a Young\'s modulus of 200 GPa, what does this indicate?

Options:

Correct Answer: It is very elastic

Solution:

A high Young\'s modulus indicates that the material is very elastic.

If a material has a Young's modulus of 200 GPa, what does this indicate?

If a material has a Young's modulus of 200 GPa, what does this indicate?

Step 1: Understand what Young's modulus is. It measures how much a material will stretch or compress when a force is applied.
Step 2: Recognize that Young's modulus is expressed in gigapascals (GPa), which is a unit of pressure or stress.
Step 3: Note that a Young's modulus of 200 GPa is considered high, meaning the material is stiff and does not easily deform.
Step 4: Conclude that a high Young's modulus indicates that the material is very elastic, meaning it can return to its original shape after the force is removed.

Young's Modulus – Young's modulus is a measure of the stiffness of a material, indicating how much it will deform under stress.
Elasticity – Elasticity refers to the ability of a material to return to its original shape after being deformed.
