The ratio of strees and strain of a wire is 3:2. Find the co-efficient of elasticity. Express the result in SI unit system.

Explanation

The ratio of stress and strain of a wire is 3:2.
SI unit of stress `=("Force")/("Area")=N/(m^(2))Nm^(-2)`
Strain is dimensionless variable.
So,co-efficient of elasticity of a wire is `=("Stress")/("Strain")`
`=(3Nm^(-2))/(2("No unit"))=1.5Nm^(-2)`
