parts, supplying the forces S, R,and T to replace the cut members and consider the equi-librium of the left-hand part of the frame. The external applied forces ab and ea can be replacedby their resultant eb whose line of action passes thru the TWO-DIMENSIONAL STRUCTUEES 6l intersection of the sides… … Fig. 44 The solution can now be completed, by the method out-lined imder the equilibrium for four forces, as indicatedby the heavy lines in the figure. These results may beobtained just as readily by considering the right-handpart of the frame as a free body. Do this. 62 APPLIED STATICS
