Question

Figure shows the applied force versus extension graph for a metal wire.

Column I	Column II
(a) Point A on curve	(p) Yield point
(b) Point B on curve	(q) Breaking point
(c) Portion ABC on curve	(r) Elastic limit
(d) Point C on curve	(s) Plastic range

• A. a-r,b-s,c-q,d-p
• B. a-s,b-q,c-p,d-r
• C. a-r,b-p,c-s,d-q
• D. a-q,b-p,c-r,d-s

Answer 1

The correct option is C a-r,b-p,c-s,d-q

Pt $A$ is elastic limit.
Pt $B$ is yield point.
portion $ABC$ is plastic range.
point $c$ is breaking pt.
$\therefore$ $a-r,b-p,c-s,d-q$.
