Determine the force in each member of the loaded truss. All triangles are 3-4-5. Enter a positive number if the member is in tension, negative if in compression. A 28 KN B H C I 15kN G -4 panels at 8 m- 23 KN D F E
Consider joint D next. The Free-Body diagram is shown. All members are drawn as if in tension (even those that we know are in compression). Use this diagram to find the forces DI and DG. Use a positive number if in tension, a negative number if in compression. DI DG CD Answers: DI = i DG = i DF 23 KN D kN KN DE
