Question

Calculate the strain produced in a wire under tension when its stress is 12×10^5Kg/m^2 ,for material is 2×10^6Kg/m^2​

Answer 1

Explanation:

Y = stress/strain

strain = stress/Y

= 12*10^5/2*10^6

= 0.6

Answer 2

Thus the strain in the wire is 0.6

Explanation:

We are given that:

• Stress in the wire = 12×10^5 Kg/m^2
• Young's modulus "Y" = 2×10^6 Kg/m^2​

Solution:

We know that

Young's modulus = Stress / Strain

2×10^6 ​ = 12 x 10^5 / Strain

Strain = 12 x 10^5 / 2×10^6

Strain = 6 / 10 = 0.6

Thus the strain in the wire is 0.6
