Problem 3.5 Determine the forces in all members of the below structure using the method of joints...
For the following trusses determine the forces in all members
using the method of joints. Specify whether the member is in
tension or compression.

F1 = 695 lb F2 = 271 lb L = 3 ft 1 h = 2.25 ft .1 Use the method of joints to determine the forces in members (BC, BD, BE and CE) and state if the members are in tension or in compression. 2. Use the method of sections to determine the forces in members (DF, EF and EG) and state if the members are in tension or in compression.
F1 = 775 lb F2 = 499 lb L = 4 ft h = 3 ft 1- Use the method of joints to determine the forces in members (BC, BD, BE and CE) and state if the members are in tension or in compression. 2- Use the method of sections to determine the forces in members (DF, EF and EG) and state if the members are in tension or in compression.
1. Determine the force in all members of the truss using the method of joints 2. Determine the force in members DE,DB and AB using the method of sections To begin the analyse linear unknown forces a of the joints in Figure criteria. Therefore, we equations applied to the © = 0 M = 0 - 10 OXF, = 0 OK B 10 kip to 3 ft to 3 ft + 3 ft 3 ft . (a)
F1 = 871 lb F2 = 228 lb L=7ft h=5.25 ft 1 Use the method of joints to determine the forces in members BC BD. BE and CE) and state if the members are in tension or in compression 2 Use the method of sections to determine the forces in members (DF. EF and EG) and state if the members are in tension or in compression.
Using the method of sections, determine the forces in the indicated members of the trusses shown and state if the member is in tension or compression. In addition, summarize the results on a force summation diagram. Notes: o Answers without a force summation diagram will receive a score of zero. Be sure to draw the free-body diagram(s) of the portion(s) of the section(s) used for analysis. Answers without the diagram(s) will receive a score of zero. Show your work. Answers...
Using the method of joints, find forces in all members of the truss. Indicate whether the members are intension or compression
For the Howe roof truss shown below: (a) List any members that have zero force [2 points] (b)Using the Method of joints, determine the force in member BD and state whether it is in tension or compression, if member AB is in compression with force of 1500lb.

Use
the METHOD OF JOINTS to determine all member forces and indicate if
the members are in compression or in tension (report the findings in a proper results sketch).
