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