The stain-stress curves of three wires of different material are showm in the figure P,Q,R are the elastic limits of the wires, the figure shows that

A

elasticity of wire P is maximum

B

elasitcity of wire R is maximum

C

tensile strenght of R is maximum

D

None the above

Text Solution

Verified by Experts

The correct Answer is:
B
(b)As stress is shown on x-axis and strain on y-axis.
So, we can say that y=`"cot"theta=(1)/("tan"theta)=(1)/("slope")`
So, elasticity of wire P is minimum and R is maximum.
