The influence ordinates for the outer and inner trusses for curved track &re found in the same manner as those for reactions or shears from the formulae Ordin. = r-(b + 2e + b 2qh) and Ordin. = —(b - 2e) respectively. Their calculations willnot be shown here. The maximum bending moments at different panel points ineach truss for straight track from Coopers E-50 loading are givenin Table 8 with the influence areas and equivalent uniform influence areas and the
