A) elasticity of wire P is maximum
B) elasticity of wire 0 is maximum
C) tensile strength of R is maximum
D) None of the above is true
Correct Answer: C
Solution :
On the graph stress is represented on x-axis and strain y-axis So from the graph \[{{U}_{(x)}}\][where, \[\frac{4}{3}M{{l}^{2}}\] is the angle from stress axis] \[\frac{M{{l}^{2}}}{3}\]\[\frac{M{{l}^{2}}}{6}\]\[\frac{2}{3}M{{l}^{2}}\] We can say that elasticity of wire P is minimum and R is maximum.
