Define :(a) Breaking stress(b) Plastic region(c) Compressibility

1.	Define :(a) Breaking stress(b) Plastic region(c) Compressibility
Answer» (a) Breaking stress: The stress corresponding to which a wire breaks is called breaking stress. Breaking force = Breaking stress * area of cross-section of the wire (b) Plastic region: The region of stress- strain curve between the elastic limit and the breaking point is called plastic region. (c) Compressibility: The reciprocal of the bulk modulus of a material is called compressibility. Compressibility = 1/k

Answer»

(a) Breaking stress: The stress corresponding to which a wire breaks is called breaking stress.

Breaking force = Breaking stress * area of cross-section of the wire

(b) Plastic region: The region of stress- strain curve between the elastic limit and the breaking point is called plastic region.

(c) Compressibility: The reciprocal of the bulk modulus of a material is called compressibility.

Compressibility = 1/k
