The structure shown is made of many weightless, solid and rigid members pinned together at different joints. The whole structure is pinned to the floor at point I and supported by a roller at point J. Two loads (F = 1N) are applied on the structure at points A and B. On the diagram, indicate where you cut the structure, in order to find the force in member GH.

Example 3.7 Determine the force developed in each member of the space truss and state if the members are in tension or compression. The crate has a weight of 5 kN. Z. -2 m. 2 m C 2 m B A 2 m

Determine the load P at which member AE would buckle. All connections in the truss are pin connections. Assume that member AE has a vertical dimension of 120 mm and a horizontal dimension of 29 mm. The modulus of elasticity of the truss members is 200 GPa. Express your answer to the nearest whole kN.
