engineering recuitment HPCL Engineer Mock Test 2024 Strength of Materials Simple Stress and Strain Stress and Strain
The length of a wire increases by l due to force F applied on it. Then, the work done W in stretching the wire will be
1
\(W\, = \,F.\,l\)
2
\(W\, = \,\frac{{F.\,l}}{4}\)
3
\(W\, = \,\frac{{F.\,l}}{2}\)
4
\(W\, = \,\frac{{F.\,l}}{3}\)
