1.	What is meant by Breaking of Wire ? What are the applications of breaking force ?
Answer» When the wire is loaded beyond the elastic limit, then strain increases much more rapidly. The maximum stress corresponding to B (see stress-strain curve) after which the wire begin to flow and breaks, is called breaking stress or tensile strength and the force by application of which the wire breaks is called the breaking force. (i) Breaking force depends upon the area of cross-section of the wire. (ii) Breaking stress is a constant for a given material. (iii) Breaking force is independent of the length of wire. (iv) Breaking force α πr². (v) Length of wire if it breaks by its own weight L = P/dg

Answer»

When the wire is loaded beyond the elastic limit, then strain increases much more rapidly. The maximum stress corresponding to B (see stress-strain curve) after which the wire begin to flow and breaks, is called breaking stress or tensile strength and the force by application of which the wire breaks is called the breaking force.

(i) Breaking force depends upon the area of cross-section of the wire.

(ii) Breaking stress is a constant for a given material.

(iii) Breaking force is independent of the length of wire.

(iv) Breaking force α πr².

(v) Length of wire if it breaks by its own weight

L = P/dg
