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 ?

The nature of elastic forces by virtue of which a body possess the property of elasticity is

Two blocks of mass m_(1) and m_(2) are moving along a smooth horizontal floor. A non-ideal spring is attached at the back of mass m_(2) . Initial velocities of the blocks are u_(1) and u_(2) as shown, with u_(1) gt u_(2) . After collision the two blocks were found to be moving with velocities V_(1) and V_(2) respectively. Find the ratio of impulse (on each block) during the deformation phase of the spring and that during its restoration phase. [By non ideal spring we mean that it does not completely regain its original shape after deformation. You can neglect the mass of the spring.]

Assertion Upto the elastic limit, strain prop stress. Reason Upto elastic limit, material returns to its original shape and size, when external force is removed.
