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 + 2j m + r – 2j m + r – 3j m – r + 2j m + r + 2j m + r – 2j m + r – 3j m – r + 2j ANSWER DOWNLOAD EXAMIANS APP
Structural Analysis A simply supported beam deflects by 5 mm when it is subjected to a concentrated load of 10 kN at its centre. What will be deflection in a 1/10 model of the beam if the model is subjected to a 1 kN load at its centre ? 5 mm 0.005mm 0.5 mm 0.05 mm 5 mm 0.005mm 0.5 mm 0.05 mm ANSWER DOWNLOAD EXAMIANS APP
Structural Analysis When a uniformly distributed load, shorter than the span of the girder, moves from left to right, then the conditions for maximum bending moment at a section is that the tail of the load reaches the section the load position should be such that the section divides it equally on both sides the load position should be such that the section divides the load in the same ratio as it divides the span the head of the load reaches the section the tail of the load reaches the section the load position should be such that the section divides it equally on both sides the load position should be such that the section divides the load in the same ratio as it divides the span the head of the load reaches the section ANSWER DOWNLOAD EXAMIANS APP
Structural Analysis The degree of static indeterminacy of a rigid-jointed space frame is (where m, r and j have their usual meanings) m + r – 2j 3m + r – 3j 6m + r – 6j m + r – 3j m + r – 2j 3m + r – 3j 6m + r – 6j 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 (3m + r) = 3j (m + 3r) = 3j (m + r) = 2j (m + r) = 3j (3m + r) = 3j (m + 3r) = 3j (m + r) = 2j ANSWER DOWNLOAD EXAMIANS APP
