Question

When a force is applied to the free end of a metal wire, metal wire undergoes
(A) longitudinal and lateral extension.
(B) longitudinal extension and lateral contraction
(C) longitudinal contraction and lateral extension.
(D) longitudinal and lateral contraction. ​

Answer 1

Answer:

B) Longitudinal extent ion and lateral contraction

Answer 2

option (B) is the correct answer

Explanation:

• option (b) is the correct answer

• When a force is applied to the free end of a metal wire, longitudinal extension and lateral contraction take place.

• An elastic material's longitudinal extension is quite tiny. The material must be in the shape of a long thin wire in order to have an appreciable change.

• lateral contraction occurs When a body is subjected to longitudinal stress, it will stretch in the stress's direction while contracting in the transverse or lateral direction (in the case of tensile stress).
