Topic: Mechanics of Materials
Governing differential equation for small deflections of elastic beams is given by
- A. EI(d²y/dx²) = M
- B. EI(d³y/dx³) = V(x)
- C. EI(d⁴y/dx⁴) = q(x)
- D. All the above
Answer: D. All the above
Explanation: All three equations are part of the governing differential equations for elastic beams, representing bending moment, shear force, and distributed load respectively.
