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