engineering recuitment UPPSC AE Mock Test 2024 Structural Analysis Determinacy and Indeterminacy Static Indeterminacy
If there are m unknown member forces, r unknown reaction components and j number of joints, then the degree of static indeterminacy of a pin-jointed plane frame is given by:
1
m + r - 3j
2
m - r + 2j
3
m + r - 2j
4
m + r + 2j
