Question

draw stress strain curve for a loaded wire.on the graph mark
a.Hooke's law
b.elastic limit
c.yield point
d.breaking point​

Answer 1

Answer:

Explanation:

graph:

the shaded region is a) hooke’s law

Answer 2

The image attached below shows various marks like Hooke's law, elastic limit , etc., on the graph.

Explanation:

• The line from O to A describes the stress is directly proportional to the strain.
• The upper yield point that is described by point B means that the material can be with stand and it doesn't undergo the the formation until this.
• The point C maintain the plastic behavior of the material.
• The ultimate stress point is described by the point D and it is the peak point in strain and stress graph.
• The point E is the breaking down point where a material brakes in more than one part.
• Young modulus is stated as the ratio of stress and strain.
• Therefore, a graph is also called Young's modulus graph of metallic wire.
