Reactions at the Points of Support of Continuous Beams. 275 



Again the curves A HA! and A FA, show the loads acting at A , 

 which have their moments about A] and A 2 respectively, equal to 

 the moments of the loads on AqAx and A A.> about A x and A 2 respec- 

 tively. 



Hence 1S L = area AoDEAaAiHAo x 60 = 16330. 



N 2 = area A DE A 3 A 3 FA x 160 = 12084. 



Similarly the curve A BCA 3 in fig. 4 is the M/I curves for 100- 

 ton load acting at A b whence 



»/ = area AoDEAsAxHAo x — — 37*67. 



n 2 ' = area A DEA 3 A,FA x — = 22 47.

Again the curve A BCA 3 in fig. 5 shows the M/I curve for 100 

 tons load acting at A 2 . 



60 



whence »i" = area AuDEA 3 A!HA x — = 22*53. 



fin 



n 2 " = area A DEA„A 2 FA<, x — = 22*69.
