Example 4.10 Determine the force in each member of the compound truss shown in Fig. 4.25(a). Solution Static Determinacy The truss has 11 members and 7 joints and is supported by 3 reactions. Since m þ r ¼ 2j and the reactions and the members of the truss are properly arranged, it is statically determinate. The slopes of the inclined

Example 4.7 Determine the forces in members CD;DG, and GH of the truss shown in Fig. 4.22(a) by the method of sections. Solution Section aa As shown in Fig. 4.22(a), a section aa is passed through the three members of interest, CD;DG, and GH, cutting the truss into two portions, ACGE and DHI. To avoid the calculation of support reactions,

Example 4.3 Identify all zero-force members in the Fink roof truss subjected to an unbalanced snow load, as shown in Fig. 4.18. Solution It can be seen from the figure that at joint B, three members, AB;BC, and BJ, are connected, of which AB and BC are collinear and BJ is not. Since no external loads are applied at joint
