Question

When a wire is stretched with a very large

force it breaks.

a) Represent the variation of extension

with load on a graph
b) Discuss the behaviour of wire at

various stages.

c) State Hooke’s law. For which part of

the above graph is this applicable.

d) Which is more elastic; steel or

rubber? Why?

Answer 1

your answer is ----


your answer from a to b in the attachment.


• Hooke's law :- Hooke’s law, law of elasticitydiscovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformationsof an object, the displacement or size of the deformation is directly proportional to the deforming force.

in graph this law is applicable from O to A


• steel is more Elastic than rubber because steel have high tendency to regain it's original configuration up to it's elastic limit or at which point wire break

Answer 2

• Hooke's law :- Hooke’s law, law of elasticitydiscovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformationsof an object, the displacement or size of the deformation is directly proportional to the deforming force.
