Match List-I with List-II : (A) A force that restores an elastic body of unit area to its original state (I)

Question

Match List-I with List-II :

	List-I		List-II
(A)	A force that restores an elastic body of unit area to its original state	(I)	Bulk modulus
(B)	Two equal and opposite forces parallel to opposite faces	(II)	Young's modulus
(C)	Forces perpendicular everywhere to the surface per unit area same everywhere	(III)	Stress
(D)	Two equal and opposite forces perpendicular to opposite faces	(IV)	Shear modulus

Choose the correct answer from the options given below : 

(1) (A)-(II), (B)-(IV), (C)-(I), (D)-(III) 

(2) (A)-(IV), (B)-(II), (C)-(III), (D)-(I) 

(3) (A)-(III), (B)-(IV), (C)-(I), (D)-(II) 

(4) (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Answer 1

Correct option is : (3) (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(A) stress \(=\frac{F_{\text {restoring }}}{A}\)

If \(\mathrm{A}=1\)

Stress \(=\mathrm{F}_{\text {restoring }}\)

(A)-(III)

(B)

\(⇒\) Shear stress 

(B)-(IV) 

(C)

\(⇒\) Volumetric stress 

(C)-(1)

(D)

\(⇒\) Longitudinal stress

(D)-(II)
