Answer Posted / lavanya v
steel is more elastic than rubber,let us cnosider two rods of rubber and steel each and let Yr and Ys be the young's modulus of elasticity when you apply load on them then length of rubber will be more than that of steel rod then
Yr/Ys=lr/ls>1 ie.Ys>Yr
therefore steel is more elastic han rubber
