Select the correct order with regard to elasticity of materials.(a) Steel > Glass > Rubber(b) Glass > Rubber > Steel(c) Rubber > Glass > Steel(d) Rubber > Steel > GlassThis question was addressed to me in a national level competition.Question is from Elastic Behaviour of Solids topic in section Mechanical Properties of Solids of Physics – Class 11

Answer»

The correct answer is (a) Steel > Glass > Rubber

Easiest explanation: Elasticity is the PROPERTY of a material to regain shape when deforming FORCES are REMOVED. Out of the three, for the same stress, steel will SHOW MUCH less or maybe no permanent deformation as compared to glass which in turn will show less permanent deformation than rubber. Remember all this comparison is for the same amount of stress.
