Question

How are we able to break the wire by repeated bendings

Answer 1

because on a repeated bending on a particular wires on a particular place its strength get lower. and really we are able to break it

Answer 2

We are able to break the wall by repeated bending, because -

• When we bend a wire,a great amount of stress (force) is applied on the bending point of the wire.

• Now,when we repeatedly bend a wire,we are actually repeatedly applying stress on the bending point.

• This repeated application of stress, breaks the elasticity of the wire after some repeated bends and when the stress becomes to overcome the elastic limit of the wire,the wire breaks apart.
