Diagram shows the stress-strain graph for a metal wire. In the graph, the region in which Hooke's law is obeyed. The ultimate strength and fracture points are represented by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
In the region 
, the graph is linear showing that stress is proportional to the strain. Thus, in
this region Hooke's law is obeyed.
The point D on the graph is known as ultimate tensile strength.
The point E on the graph is known as fracture point.
