Question

a rubber band originally 30cm long is streched to a length of 32 cm by a certain load. What is the strain produced?​

Answer 1

The strain is equal to "0.0667".

Explanation:

Given,

Length(l) = 30 cm

∴ Elongation(Δl) = 32 cm - 30 cm = 2 cm

We know that,

Strain = $\dfrac{\delta\ l}{l}$

∴ Strain = $\dfrac{2}{30}$

= $\dfrac{1}{15}$

= 0.0667

Hence, strain is equal to "0.0667".
