Mechanical Engineering QUESTION #2503
Question 1
A simply supported beam with uniformly distributed load \(w\) (N/m) over span \(L\) has a maximum bending moment of:
  • \(M_{max} = \frac{wL}{8}\)
  • \(M_{max} = \frac{wL^2}{4}\)
  • \(M_{max} = \frac{wL^2}{8}\)✔️
  • \(M_{max} = \frac{wL^2}{2}\)
Correct Answer Explanation
For a simply supported beam with UDL \(w\) over span \(L\): the maximum bending moment occurs at mid-span and equals \(M_{max} = wL^2/8\).
