befixed in the direction of OX at 0, butthe coordinates x and y are measuredfrom the point of application A of theload P as shown in the figure. Ifright-hand moments are positive, andleft-hand negative, the componentP sin a will have the negative moment—P sin ax about any point 0. Thelever arm of P… … Fig. I. For any number of forces or loads P there will obviouslybe a corresponding number of pairs of terms in the third 176 FLEXURE. [Ch. IT. member of eq. (i). It will therefore be sufficient to treatone force P only. Eq. (i) may be put in the form, d^y ,9 P sin a . . j^+n^y= -^j-x=mx . „ , . (2)…
