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 – 3j m + r + 2j m + r – 2j m – r + 2j m + r – 3j m + r + 2j m + r – 2j 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 head of the load reaches the section the load position should be such that the section divides the load in the same ratio as it divides the span the tail of the load reaches the section the load position should be such that the section divides it equally on both sides the head of the load reaches the section the load position should be such that the section divides the load in the same ratio as it divides the span ANSWER DOWNLOAD EXAMIANS APP
