Question

The stress-strain curve for mild steel is shown in figure given below. Choose the correct option referring to both figure and table.

Point on the graph	Description of the point
P	1.Upper yield point
Q	2.Ultimate tensile strength
R	3.Proportionality limit
S	4.Elastic limit
T	5.Lower yield point
U	6.Failure

• A. P-1,Q-2,R-3,S-4,T-5,U-6
• B. P-3,Q-1,R-4,S-2,T-6,U-5
• C. P-3,Q-4,R-1,S-5,T-2,U-6
• D. P-4,Q-1,R-5,S-2,T-3,U-6

Answer 1

The correct option is C P-3,Q-4,R-1,S-5,T-2,U-6

P:Proportional limit Q:Elastic limit
R:Upper yield point S:Lower yield point
T:Ultimate tensile strength
U:Failure/Rupture
