9. A wire increases by 10-3 of its length when a stress of 1x10 Nm-2 is applied to it. Calculate the Young modulus of the wire.​

Respuesta :

Answer:

[tex]E = 1 \times 10^3 \: N/m^2[/tex]

Explanation:

We know ,

  • E = stress/strain

here

  • E represents Young modulus

here we have,

  • stress = 1 × 10 N/m²
  • strain = [tex] {10}^{ - 3} [/tex] m

substitute the values

[tex]E= \dfrac{1 \times 10}{10^{-3}}[/tex]

[tex]E = 1 \times 10^3 \: N/m^2[/tex]
