Structural Analysis 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) (m + r) = 3j (3m + r) = 3j (m + r) = 2j (m + 3r) = 3j (m + r) = 3j (3m + r) = 3j (m + r) = 2j (m + 3r) = 3j ANSWER DOWNLOAD EXAMIANS APP
