Question

The point on stress-strain curve at which
strain begins to increase even without
increase in stress is called....
(A) elastic point (B) yield point
C) breaking point (D) neck point​

Answer 1

Answer:

(b)yield point

Explanation:

Answer 2

The point on the "stress-strain curve" at which  the strain begins to increase even "without  the increase in stress" is called yield point.

Option - B

Explanation:

• We are aware of below that is given by "hook and the curve" that shows the relation between the stress and strain, is determines the yield of a material.
• The point at which the stress and strain curve actually starts curving up is the point known as yield point at this point.
• The elastic limit is obtained and further application of strain makes it acting like a plastic until the object or elastic attains the fracture point.
