A) \[\frac{S}{2Y}\]
B) \[\frac{2Y}{{{S}^{2}}}\]
C) \[\frac{{{S}^{2}}}{2Y}\]
D) \[\frac{{{S}^{2}}}{Y}\]
Correct Answer: C
Solution :
The elastic energy density stored in wire = Energy stored in unit volume of wire \[=\frac{1}{2}\times \] stress \[\times \] strain \[=\frac{1}{2}\frac{{{\left( Stress \right)}^{2}}}{Y}=\frac{{{S}^{2}}}{2Y}\]You need to login to perform this action.
