is there any change in elasticity of metal with change in temperature?

Answer 1

Depends on the metal, generally yes.

Answer 2

Generally speaking, there is a change in elasticity with temperature - particularly for metals.

ELASTICITY is defined as the ratio of STRESS / STRAIN.

STRESS = force per unit area, and STRAIN = change in dimension (typically length).

Since most metals tend to expand somewhat when heated, a given stress level can be achieved by increasing the force as the cross-section increases. With the cross-section increasing as a result of temperature, the numerator of the ELASTICITY equation is increasing as well.

However, the range over which this phenomena occurs is somewhat limited; some materials have wider elasticity ranges than others. Also, the direction of the force must be taken into account - elasticity is not necessarily the same in all directions for a given material.

Answer 3

Yes, as the temperature of the metal increases, the bonds between the metal breaks or weakens therefore increasing the Elasticity of the Metal.

Answer 4

Depends on the temperature, hot temperatures usually make metals more pliable. The hotter it gets, the more the metal will turn into a liquid (this is 1000s of degrees C) Cold temperatures usually make metals more brittle. Depending on the metals this could occur in great degrees of change, or in just a few small degrees of change.

Answer 5

Direct proportionality. Increase in temperature results in an increase in elasticity.

Answer 6

Yes of course

Every property of something changes when the temperature changes.

Answer 7

Unless its a spring ... any normal temp w/o thermal enhancement to metal should not effect it greatly

Answer 8

depending on what kind of material u r using it varies

Answer 9

YES, OF COURSE
