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. Part 1 BI Part 2 ✔Correct Answer: Cl=0 BH= 0 DF = 0 Part 3 Hint Consider jointi. The Free-Body diagram is shown. All members are assumed to be in tension. Use this diagram to find the force in Cl. Use a positive number if in tension, a negative number if in compression. CI BC eTextbook and Media A₂ 19 KN Correct ✓ Correct B Answers: Hint Part 5 We can also see that Bi-Di BC= 13.125 CD= -13.125 H Examine joints Fand H in order to find the foces in BH and DF. Answers: Answer: Ng= 43.8125 EF We also learn that AH = GH and EF = FG. Answers: DE 1 BA EF=1 eTextbook and Media Consider joint C next. The Free-Body diagram is shown. All members are assumed to be in tension. C G 4 panels at 8 m- I Use this diagram to find the forces BC and CD. Use a positive number if in tension, a negative number if in compression.
