Which one is more elastic rubber or steel? Explain.

The property of a body by virtue of which it tends to regain its original conifguration as soon as the deforming forces applied on the body are removed is called elasticity. Coefficient of elasticity, E = (stress)/("strain") = (F//a)/(Delta l//l) = (F l)/(pi r^2(Delta l)) The value of E depends upon nature of meterial. A meterial with higher value of E is said to be more elastic. Read the above passage and answer the following question : (i) Which is more elastic steel or rubber ? Why ? (ii) What values of life so you learn from this concept ?

Steel is more elastic than rubber because it :

Which of the following is more elastic ?

a. Glass is more elastic than rubber b. Rubber is miore elastic than glass c. Steel is more elastic than rubber d. Rubber is more elastic than steel For the above statements

Assertion : Steel is more elastic than rubber. Reason : Under given deforming force, steel is deformed less than rubber.
