(Answered): Forces in a 2D TrussI got a 50 on this quiz and Idon't know-how, I got KJ and GR are zero force memb ...

Questions 1 - 4 compute forces in the members of the 2D truss below. The truss has an overall height of 4 meters and an overall length of 12 meters (there are 8 members along the bottom which each are 1.5 meters long). If the member is in compression, use a negative sign in the answer to indicate compression. Work in units of kN for forces but do not enter units. 20 10 KN 6 kN 6 kN 12 m 8 @ 1.5 m- Determine the force in member KJ. KJ = QUESTION 2 Determine the force in member KR. KR = QUESTION 3 Determine the force in member GR. GR = QUESTION 4 Determine the force in member GH. GH =
