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 incompression BI Answer:CI-0 13 KN Answers: Consider joint & The Free-Body diagram is shown. All members are assumed to be in tension. Use this diagram to find the force in CI. Use a positive number if in tension, a negative number if in compression. CI BHO H DF 0 G 4 panels at 8 m- I 18KN Examine joints F and Hin order to find the foces in i sin BH and DF. KN KN 16 KN D KN DI
Consider joint C next. The Free-Body diagram is shown. All members are assumed to be in tension. Use this diagram to find the forces BC and CD. Use a positive number if in tension, a negative number if in compression. C 18 KN BC Answers: BC- 11.25 CD--1125 CI KN KN CD Every other joint in the truss has more than two unknowns. Time to switch tactics. Here is a Free-Body diagram for the entire truss. Solve for the reaction Ng under the roller at E. > Answer: Ne- 13 KN H G -4 panels at 8 m- KN 18 KN 2 F 16 KN D E
