For heavily reinforced concrete member, the nominal maximum size of the aggregates should be restricted to

When a series of wheel loads crosses a simply supported girder, the maximum bending moment under any given wheel load occurs when

The maximum bending moment due to a train of wheel loads on a simply supported girder

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

For the stability of a structural part, the weight or anchorage should be
