Q: Indeterminacy in the structure may result from (a) Multiple reactions (b) Extra bars in truss (c) Fixed supports in frames (d) Geometry of the structures
  • A. Only (a), (b) and (c)
  • B. Only (b), (c) and (d)
  • C. None of the above
  • D. All of the above
Correct Answer: Option D - Indeterminacy in the structure based on external supports reactions and their internal member forces (geometry), extra bars in truss and fixed supports in frames (degree of freedom).
D. Indeterminacy in the structure based on external supports reactions and their internal member forces (geometry), extra bars in truss and fixed supports in frames (degree of freedom).

Explanations:

Indeterminacy in the structure based on external supports reactions and their internal member forces (geometry), extra bars in truss and fixed supports in frames (degree of freedom).
