Why are sound waves called mechanical waves ?

Transverse mechanical waves cannot be propagated through

What is a wave ? What are elastic waves ?

(A): Transverse mechanical waves can not propagates in liquids and gases. (R): Liquids and gases flow when acted on by shearing stress, they can not sustain shear stress

The radio and TV programs, telecast at the studio, reach our antenna by wave motion. Is it a mechanical wave or nonmechanical ?

(A): Both transverse and longitudinal mechanical waves can travel through solids, whereas only longitudinal mechanical waves can travel through gases. (R): Gases do not have rigidity modulus.
