The space truss is supported by a ball-and-socket joint at A and short links, two at C and one at D . Determine the x, y, z components of reaction at A and the force in each link.

[A].
A_{x} = -1.050 kN, A_{y} = 1.050 kN, A_{z} = 0.800 kN, C_{y} = -1.050 kN, C_{z} = 0.600 kN, D_{x} = 1.050 kN [B].
A_{x} = -1.400 kN, A_{y} = 1.400 kN, A_{z} = 0.800 kN, C_{y} = -1.400 kN, C_{z} = 0.600 kN, D_{x} = 1.400 kN [C].
A_{x} = -2.49 kN, A_{y} = 1.867 kN, A_{z} = 0.800 kN, C_{y} = -2.49 kN, C_{z} = 0.600 kN, D_{x} = 2.49 kN [D].
A_{x} = -1.867 kN, A_{y} = 1.867 kN, A_{z} = 0.800 kN, C_{y} = -1.867 kN, C_{z} = 0.600 kN, D_{x} = 1.867 kN
