Question

The length of a wire is reduced to half of its initial value. What will be the effect on the increase in its length under a given load?

Answer 1

Answer:

The simplest answer is that "there will be no effect on the maximum load.

When stress is applied to a wire beyond it's elastic limit this tend to break as the result of increasing strain on the wire. The force at this point applied are normally known as the break force which can bring fracture to a body.This force don't depends on the length just depends on the cross sectional area of the wire.The stress applied that cause breakage at this point also don't depend on the size instead depends on the material which the wire is made of.

In short the strain only depends force and unit area so whether or not the length change it does does not effect the maximum load.

Answer 2

Answer:

Its change/increase in length will be halved if the length is halved

FL/Ay = delta l
