The stress-strain curves for brass, steel and rubber are shown in the figure. The lines $A, B$ and $C$ are for

A

Rubber, brass and steel respectively

B

Brass, steel and rubber respectively

C

Steel, brass and rubber respectively

D

Steel, rubber and brass respectively

Solution

(c) $Y = \tan \theta $. According to figure ${\theta _A} > {\theta _B} > {\theta _C}$

i.e. $\tan {\theta _A} > \tan {\theta _B} > \tan {\theta _C}$

or ${Y_A} > {Y_B} > {Y_C}$

$ A, B,$ and $C$ graph are for steel, brass and rubber respectively.
