Questions & Step-by-Step Solutions
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.
