railway RRB JE (CBT I + CBT II) Mock Test 2024 Strength of Materials Deflection of Beam Methods of Determining Deflection of Beam
The differential equation of flexure is:
1
\(EI\frac{{{d^2}y}}{{d{x^2}}} = - M\)
2
\(EI\frac{{{d}y}}{{d{x}}} = M^2\)
3
\(EI\frac{{{d^2}y}}{{d{x^2}}} = M^2\)
4
\(M\frac{{{d^2}y}}{{d{x^2}}} = -EI\)
