Extracted text: F2 F1 a -2 m- -2 m- -2 m E 1.5 m F3 G 1.5 m F4 1.5 m Determine the reaction at support F and the force in members ED, EH, and GH of the truss. Tension is positive and compression is negative. Use F1 = 130 kN, F2 = 5 kN, F3 = 75 kN, and F4 = 220 kN for your calculations. You are encouraged to use the method of sections for determining the forces in the three members. The magnitude of the vertical reaction force at support F in kN (round to one decimal place): kN The force in member DE in kN (round to one decimal place): kN The force in member GH in kN (round to one decimal place): kN The force in member EH in kN (round to one decimal place): kN
