Question

Q58. What is the point P shown on the stress strain curve?
O (A) Upper yield point
(B) Yield plateau
(c) Proportionality limit
3
2
(D) Ultimate point​

Answer 1

Answer:

The point P shown on the stress strain curve  is Proportionality limit.

Explanation:

The breaking point of a substance is the point at which it breaks. The last point on the stress-strain curve will be the breaking point.

The proportional limit is defined as the point P.

As a result, the proportional limit is the point at which the stress-strain curve deviates from a straight line for the first time.

As a result, up to the point where the first straight line begins.

As a result, up to the proportionality limit.
