engineering recuitment BPSC AE Mock Test 2025 Structural Analysis Determinacy and Indeterminacy Static Indeterminacy
If there are (m) unknown member forces, (r) unknown reaction components and (j) number of joints, the degree of kinematic indeterminacy of a pin-jointed plane frame is given by :
1
2j - r
2
j - 2r
3
3j - r
4
2j + r
