# What to do when the forces on a truss is not on the joints

How would i resolve the forces so they are acting on the bottom joints.

We consider each member that has mid-span loads as a simply supported beam and resolve the loads on the beam to vertical reactions and those reactions will be loads at those joints.

$$\Sigma M_B=0 \ 312*5.05/6.7= 235kN =P_A \rightarrow \ and \ 312-235= 77=P _B$$
