Senior Supply Chain Management Engineer Interview Questions and Answers

Elongation is the percentage increase in length of a material before it fractures. Yield strength is the stress at which a material begins to deform plastically.

• Elongation is a measure of ductility and is expressed as a percentage of the original length of the material.

• Yield strength is the stress at which a material begins to deform plastically and is expressed in units of force per unit area.

• Both elongation and yield strength are important mechanical properties of materials...read more

Young's modulus is a measure of the stiffness of a material.

• It is also known as the modulus of elasticity.

• It is defined as the ratio of stress to strain in a material.

• It is a fundamental property of a material and is used to predict how it will behave under load.

• It is measured in units of pressure, such as pascals or pounds per square inch.

• For example, steel has a high Young's modulus, meaning it is very stiff and difficult to deform.
