The stress-strain graphs for materials A and B are shown in figs. (i) and (ii) (given, 
).
(i) (ii)
The graphs are drawn to the same scale.
Which of the two is the stronger material?
Text Solution
Verified by ExpertsThe correct answer is:
B
From the given figure, we can say that, the slope of the linear portion of the stress-strain curve
is greater for material B. Hence, Young's modulus of B is greater than that of material A. Material B can withstand more load without breaking.
So, it is stronger than material A and its ultimate stress is higher.
