What is more elastic iron or rubber?

Answer 1

N0.

The common belief is that if an object elongates easily the object is more elastic .

But in Physics the object which gives more resistance to elongate is said to be more elastic .

Such objects will have high Young's modulus .

Steel is more elastic than copper . The Young's modulus for steel is 210 G Pa

For copper it is 117 G Pa

Elongation for steel is 35% and for copper it is 45%

For rubber Young's modulus is 0.02 G Pa and elongation is 500 %

During collision two clay balls will stick together. We call it inelastic collision .

Two steel balls will rebound easily and the collision is elastic collision.

Answer 2

Iron has a much higher modulus of elasticity than rubber. That means it is much stiffer, and thus rubber is much more elastic, with more elasticity; that is, under a given force, and identical lengthand area, the rubber will stretch much more; in fact thousands of times more..

Answer 3

True - which is why your car has steel springs, not rubber.

Rubber deforms when stretched, steel does not (assuming you don't exceed its limits).

Answer 4

Of course not. Rubber is more elastic than iron.

Answer 5

well what are RUBBER bands made out of? and is there other name ELASTIC band?

Answer 6

computer use electromagnetic and electricity

Answer 7

Steel is more elastic
