Question
Assertion :Yield strength is the stress required to produce a small specific amount of deformation. Reason: The offset yield strength can be determined by the stress corresponding to the intersection of the stress-strain curve and a line parallel to the elastic line offset by a strain of 0.2 or 0.1%.

Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A→Elastic limit.B→Yield Point.After elastic limit, we required a small stress to be deformed.And in this AB region if the metal reach,then if is not possible to regain its shape.Also we can measure the yield strength by graph.
