Young's Modulus:

**Y = S/St**

Stress:

**S = Y*St**

Strain:

**St = S/Y**

**Where,**

Y = Young's Modulus,

S = Stress,

St = Strain.

Young's Modulus states that a measure of elasticity is equal to the ration of the stress acting on a substance to the strain produced. Young's Modulus is also known as modulus of elasticity. Young's modulus is one of the basic parameters in characterizing the mechanical properties of solids.

The ratio of a simple tension stress applied to a material to the resulting strain parallel to the tension.

Within the limits of elasticity, the ratio of the linear stress to the linear strain is termed the modulus of elasticity or Young's Modulus and may be written Young's Modulus, or E = (Stress/Strain)

**Example:**

Calculate the Young's Modulus or the Elasticity of modulus for the given Stress and Strain.

Stress (S) = 25 m

Strain (St) = 15 m

**Solution:**

**Apply Formula:**

Y = S/St

Y = 25/15

Y = 1.67

**Young's Modulus(Y) = 1.67**
