P:3-17 & 18 | Method of Sections Calculations | Statically determinate Trusses | Structural Analysis

3–17. Determine the force in each member of the truss in terms of the load P, and indicate whether the members are in tension or compression. 3–18. If the maximum force that any member can support is 4 kN in tension and 3 kN in compression, determine the maximum force P that can be supported at point B. Take d = 1 m.
