Question
Physics Question on mechanical properties of solids
In the above graph, point B indicates
A
Breaking point
B
limiting point
C
Yield point
D
None of theabove
Answer
Yield point
Explanation
Solution
In the graph, A is called elastic limit upto which point Hooke's law holds good. B is called yield limit which is the maximum point upto which stress is proportional to strain. C is called plastic limit, in which elongation does not occurs, if you increases the force. D is called breaking limit, where the elastic material finally breaks aways from the wire having bright stretched beyond the yield point.
