Question

which is more elastic steel or rubber?​

Answer 1

Answer:

By this definition steel is more elastic than rubber because stills come back to its original shape faster than rubber when the deforming forces are removed........ for a given stress (streching force per unit area) strain in much small earring steel then in rubber hence is the answer.......

Answer 2

Answer:

Ans : steel

Explanation:

Answer may be weird to you at first. Because,

according to young's modulus,

                                        y = fl/AΔl

here delta l is less for steel

and high for rubber (change in length)

so when the denominator become less ( steel- since small) y become high

and when the value of denominator is high( rubber- since change in length is high) y become less

(y- young's modulus)

so y is less for rubber and high for steel

therefore steel has more elasticity.
