  • (A)  the centre of gravity of the load system is midway between the centre of span and wheel load under consi-deration
  • (B)  the centre of span is midway between the centre of gravity of the load system and the wheel load under consideration
  • (C)  the wheel load under consideration is midway between the centre of span and the centre of gravity of the load system
  • (D)  none of the above
