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 load position should be such that the section divides the load in the same ratio as it divides the span the load position should be such that the section divides it equally on both sides 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 the load in the same ratio as it divides the span the load position should be such that the section divides it equally on both sides the head of the load reaches the section the tail of the load reaches the section ANSWER DOWNLOAD EXAMIANS APP
