engineering recuitment UPSSSC Assistant Boring Technician 2022 Mock Test Physics Mechanical Properties of Solids Stress and strain
A wire of length L and cross-sectional area A is made of material of Young's modulus Y. If the wire is stretched by the amount x, then the work done is
1
\(\frac{{YA{x^2}}}{{2L}}\)
2
\(\frac{{YA{x^2}}}{L}\)
3
\(\frac{{YAx}}{{2L}}\)
4
\(YA{x^2}L\)
