engineering recuitment GATE CE 2023-24 Test Series Strength of Materials Simple Stress and Strain Strain Energy
A cantilever beam of length L and flexural modulus EI is subjected to a point load P at the free end. The elastic strain energy stored in the beam due to bending (neglecting transverse shear) is
1
\(\frac{{{P^2}{L^3}}}{{6EI}}\)
2
\(\frac{{{P^2}{L^3}}}{{3EI}}\)
3
\(\frac{{P{L^3}}}{{3EI}}\)
4
\(\frac{{P{L^3}}}{{6EI}}\)
