Q. A rigid-jointed plane frame is stable and statically determinate if (Where m is number of members, r is reaction components and j is number of joints) (Solved)
1. (m + r) = 2j
2. (m + r) = 3j
3. (3m + r) = 3j
4. (m + 3r) = 3j
- c. (3m + r) = 3j
1. (m + r) = 2j
2. (m + r) = 3j
3. (3m + r) = 3j
4. (m + 3r) = 3j
