To solve for the moment and reactions of the beam shown, the three-moment equation is useful. The three moment equation is given as: 6Ab 6Aa + L1 MĄ(L1) + 2Mg(L1+ L2 + MCL2) + Assuming that there is no settlement of supports and El is constant for the whole structure. 6Aa 6Ab is called the "Factors" of the three-moment equation which can be determined by using the Moment-Area diagram of the left span and right span of the beam and also by L1 using integral calculus.
