e line ED parallel to pieceED; DE will be the required tensile stress. Knowing ED, we may now pass to the thirdupper joint. The portion CBPQ of the force polygon is already drawn. Taking the pieceED next in order, its stress being known, draw QD equal and parallel to ED; then DDparallel to QE,… … Fig. 49. APPLICATION OF THE LAWS OF EQUILIBRIUM. 29
