 For tin- poHtinii of loading formula i 17) gives 



S. = ^(g (21895) + - 287.5) 1(>8.1*. 



For maximum shears in the intermediate panels, deter- 

 mine the position of loading by formula (20a) and the shear 

 by formula (19a).

The above values for shears agree with the values gi 

 by Table 9. The wheel for maximum shear in panel- of 

 girder and truss bridges is given in Table 6.
