which is more elastic- rubber or steel.why?

i think both

steel

because a body is said to be more elastic depending upon how fast it gains its original shape after removal of external(deforming)force

when a force is applid on steel it is deformed but it immediately regains its original shape within a fraction of seconds which is not in the case of rubber

  1. its rubber as steel  is flexible not  elastic
  2. if we streaches a 2m llong rubber it would streaches to 12m
  3. but if we streaches  steel, due to its ductile nature it would remain streached 
  4. while rubber would regain its length,but steel would not.

  hence  rubber is elastic

 Being a physics teacher, I completely agree with Tapas Mohanty. The only think I'd like to add is when a force is applied on steel it is deformed but it immediately regains its original shape within a fraction of second when the deforming force is removed.

Also, the elasticity of a material is the measure of the force (stress) required to deform its shape (strain) . For steel we require a lot of force to deform a steel wire for a small change in length. In case of rubber, a small amount of force can produce a lot of deformation. Such materials, in which a small force can cause a large deformation, are called elastomers. Rubber is an elastomer.

get as many question u can get in physics (specially conceptual). I would love to answer if i could.

 Elasticity = stress/strain.Here strain =change in length/original length.For the same stress the change in length is least in steel,that is strain is very very small in steel(we can,t even observe the change in length in steel when a deforming force is applied).That is in the equation elasticity = stress/strain, the denominator strain is very small for steel there by the answer , elasticity , becomes large for steel or steel is more elastic.

i agree with tapas nd sir = STEEL

In physics the elasticity of a material is measured in terms of modulus of elasticity or Young’s modulus.

Y = stress/strain = (F/A)/(∆l/l)

In case of a steel wire a large force F will produce a small extension. Where as in a rubber band a small force will produce a large extension. So, steel has a higher value of Young’s modulus than rubber. Thus, steel is more elastic then rubber.

hahahaha......now i got what mr.channi{physics teacher }was saying for two days....yes the answer is steel
thanxfor the answer sir

Yes, its steel.
and the reason is elasticity is inversely proportional elongation.
when equal forces are applied, steel elongates less when compared to rubber.
hence, steel is more elastic than rubber.

steel is more elastic than rubber as it gains its original configuration faster than rubber when the deforming force is removed.
Hope this clarifies your doubt.

Steel, because a body is said to be more elastic depending upon how fast it gains its original shape after removal of external(deforming)force. when a force is applied on steel it is deformed but it immediately regains its original shape within a fraction of seconds which is not in the case ofrubber.

Young's modulus of steel is greater than that ofrubber. Also, steel regains its original shape more quickly than rubber.

yes it is steel

By this definition, steel is more elastic than rubber because steel comes back to its original shape faster than rubber when the deforming forces are removed.Elasticity In Physics And In Common Life: In common life we label a substance asmore elastic if it can be stretched more than others

Elasticity is determined by young s modulus .youngs modulus is inversely proportional to strain,ie change in a body due to stress. Comparing rubber and steel a greater change when stress is applied is observed in case of rubber and thus it is less elastic.i hope this helped u????

Steel.Because it has higher elasticity than rubber.

Steel is more elastic than rubber because steel regain its original shape very quickly after removal of deforming force. And shape chages at very small level which can not be seen by naked eyes.

Rubber is not an elastic material,as it do not obey the properties of rigid body.:. It is not a solid. :)

its rubber as steel? is flexible not? elastic

if we streaches a 2m llong rubber it would streaches to 12m

but if we streaches? steel, due to its ductile nature it would remain streached?

while rubber would regain its length,but steel would not.

? hence? rubber is elastic

Steel is more elastic than rubber .aacording to young's modulus two identical rod make up of rubber and steel all deformed by equal force.it is found that change in length of rubber is greater than change in length of steel.thus ,young' s modulus of rubber is less than steel .hence steel is more elastic than rubber.

Rubber is more elastic because even after applying force it regains it shape whereas steel will break after reaching the ultimate tensile strength.
