Chapter 6, Problem 21P

Determine the force in each member of the truss and state if the members are in tension or compression. Set P1 = 10 kN and P2 = 4 kN. (hint: method of joints)

1. Use the Method of Sections for this problem. Determine the force in members BC, BE, and EF of the truss and state if each member is in tension or compression. Set P1=16kN, P2=24kN. E 2 m B 2 m 1 m

Determine the force in members CD ( in kN)of the Pratt truss. State if the members are in tension or compression. Take that P1 = 24 kN , P2 =32 kN and P3 = 43 kN. Tension is (+) and Compression is (-) H 3 m D -2 m--2 m--2 m--2 m--2 m--2 m-

● Determine the force in each member of the truss and state if the members are in tension or compression. 500 lb -3 ft- B 500 lb -3 ft- 9 ft -3 ft- D OE 6 ft 6 ft

Q1: a- Identify the zero-force members in the truss. H G F E b- Determine the force in each member of the truss. State if the members are in tension or compression. 3 m B Group B: Take P = 700 kN -3 m 3 m

Determine the force in members CD of the truss, and state if the member is in tension or compression. Take P = 1285 lb  Determine the force in members HI of the truss, and state if the member is in tension or compression. Take P = 1285 lb . Determine the force in members CJ of the truss, and state if the member is in tension or compression. Take PPP = 1285 lb.

Set P1 = 7 kN and P2 = 19 kN Determine the force of every member and state whether it is tension or compression

3. Use the Method of Sections for this problem. From drawing a FBD of the entire system and summing the moments about point A, you find that the reaction force at roller D=26kN ↑.Determine the force in members EF, BE, and BC of the truss and state if these members are in tension or compression. Set P₁=18kN, P₂=24kN, and P3=12kN. 3m 3m 3 m 3m E P3 F A B P₁ P₁

Determine the force in members JI, EF, EI, and JE of the truss, and state if the members are in tension or compression. 900lb, 1000lb, 1500lb, 1000lb. 8ft,8ft,8ft,8ft,8ft,8ft,8ft,8ft,8ft. Show complete free body diagram and solutions
