Structural Analysis The degree of static indeterminacy of a pin-jointed space frame is given by (where m is number of unknown member forces, r is unknown reaction components and j is number of joints) 3m + r – 3j m + r + 3j m + r – 2j m + r – 3j 3m + r – 3j m + r + 3j m + r – 2j m + r – 3j ANSWER DOWNLOAD EXAMIANS APP
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 (m + r) = 2j (m + 3r) = 3j (3m + r) = 3j (m + r) = 3j (m + r) = 2j (m + 3r) = 3j (3m + r) = 3j ANSWER DOWNLOAD EXAMIANS APP
