Civil Engineering QUESTION #6587
Question 1
A beam is supported by three fixed supports. The degree of static indeterminacy of the beam is:
  • 3
  • 6✔️
  • 9
Correct Answer Explanation
For a beam with \(n\) fixed supports: each fixed support provides 3 reactions (vertical, horizontal, moment). Total reactions \(= 3 \times 3 = 9\). Equations of equilibrium \(= 3\). Degree of indeterminacy \(= 9 - 3 = 6\).
