90 BRIDGES. As the beam is supposed to have no weight, no load will act upon the beam between the given weights. The bending moments at the points of application of the three weights or loads will be mM1=Ra, ] M2=R(a + b)-Wxb, L . . . (16) M,=R{a-^b + c)-W1(b-Yc)-W2c. J After substituting the value… … 2 X Fig. 13. The bending produced by each weight will also be represented precisely like that in Fig. 12. The triangle ANB represents the bending produced by Wt; AOB the bending produced by W2; and APB the bending produced by W3. The resultant bending effect produced by the three loads or weights…
