Then Z X and E X fix the point X ; and X M and D M fix the point M. The Stress Diagram may now be com- pleted in the usual way, and the closing line will form a check line. Second Method for Stress Diagram. — In' Fig. 4, we have four forces in equilibrium acting at a point and their lines of action lie along two straight lines. The condition for equili- brium is, that H M is equal and opposite to K L and M L is equal and opposite to KH. The Force Polygon will therefore be a parallelogram and ma...y be represented by H M L K in the Stress Diagram, Fig. 36. From the above, it is evident that the stress in H M must be equal to the load C D and the stress in K L equal to the stress in H M. Therefore, draw A K and A L parallel to the bars A K and A L respectively and draw K L between them parallel and equal in length to C D. This will determine the points K and L in the Stress Diagram, Fig. 36, which may now be completed. The closing line will form a check as in the first method. Trapezoidal Truss of Three Panels.
