	Column I		Column II
(A)	The shape of rubber heel changes under stress	(p)	Young’s modulus of elasticity is involved
(B)	In a suspended bridge, there is a strain in the ropes by the load of the bridge	(q)	Bulk modulus of elasticity is involved
(C)	In an automobile tyre, when air is compressed, the shape of tyre changes	(r)	Modulus of rigidity is involved
(D)	A solid body is subjected to a deforming force	(s)	All the moduli of elasticity are involved

• A. A – q, B –r, C –s, D -p
• B. A –p, B –q, C –r, D –P
• C. A –r, B –q, C –p, D –s
• D. A –r, B –p, C –q, D -

Answer 1

Answer: (D)

A –r, B –p, C –q, D -

Answer 2

: The shape of rubber heel changes under stress involves modulus of rigidity as shape changes without change in volume.

A – r

The strain in the ropes of a suspended bridge involves Young’s modulus of elasticity as the extension of ropes takes place due to the load of the bridge.

B – P

In an automobile tyre, bulk modulus of elasticity is involved,

as the volume of air in the tyre changes.

C – q

A solid body when subjected to a deforming force, all the moduli of elasticity are involved.

D – s
