10 kN 10 kN 10 kN ++m- -4m

I tried to solve the first problem by cutting a section at s and then taking the sum of moments with respect to point H (HJ, HI, DJ are now not relevant) which looks like it yields compression which seems right but I keep on getting the wrong answer

Determine the force in each member of the truss and state if the members are in tension or compression. Set P₁ = 7 kN and P₂ = 7kN. A P₁ -2 m- D P₂ B 2m

Determine the forces in each member of the space truss.  Detailed solution please.

Problem 2: Determine the force in ALL the members of the truss. State if the members are in tension or compression. Show all your work to receive full credit. (Hint: It is not needed to find the reaction forces at C and E if you use the Method of Joints). Note: P1= 1000 lb and P: = 500 lb B C30 45 999 4 ft E 550 D. -4 ft- - 4 ft- 999 299
