A) \[\frac{1}{2}(A.L)\left( \frac{Yx}{L} \right)\left( \frac{x}{L} \right)\]
B) \[(A.L)(YL)\left( \frac{x}{L} \right)\]
C) \[2(A.L)(YL)\left( \frac{x}{L} \right)\]
D) \[3(A.L)(YL)\left( \frac{x}{L} \right)\]
E) \[4(A.L)(YL)\left( \frac{x}{L} \right)\]
Correct Answer: A
Solution :
Work done \[=\frac{1}{2}\times \] stress \[\times \] strain \[\times \] volume Or \[W=\frac{1}{2}Y\frac{x}{L}\times \frac{x}{L}\times AL\] \[=\frac{1}{2}(AL)\,\left( Y\frac{x}{L} \right)\,\left( \frac{x}{L} \right)\]You need to login to perform this action.
