Question

23. Draw stress-strain curve for a loaded wire. On the graph, mark
a) Proportional Emit b) tensile strength c) yield point d) fracture point​

Answer 1

Explanation:

a)Proportional limit is the point on stress strain curve where the linear and elastic deformation region transitions into a non linear and plastic deformation.

b)Tensile Strength, maximum load the material can support with out fracture.

c)Yield point, beyond the point the material enters into permanent plastic defromation.

d)fracture point, at this point material reaches its maximum strains and material gets seperated physically.
