Question

The ratio of tensile stress to tensile strain within elastic limit is called

Answer 1

The ratio of tensile stress to tensile strain within elastic limit is called as Modulus of Elasticity or Young's Modulus. It is denoted by Y or E.

Answer 2

The ratio of tensile stress to tensile strain within the elastic limit is called modulus of elasticity (Y) or Young's modulus (Y).

• The elastic modulus is the measure of the stiffness of a material.
• There are many factors affecting the modulus of elasticity such as the nature of material etc.
• The unit of modulus of elasticity is pressure units.
• The SI unit used is Pascals (Pa).
