the space truss shown in figure Q$6$ is formed by two right angled triangles ABC and DEF that are joined together by members BD$,$ BE$,$ CD and CF$.$ The truss is supported by ball and socket joint at A and B$.$ Joint C and F are supported by roller that prevent translation in the z direction. $10$ kN point loads at joint B and F act horizontally in the y$-$direction, while $10$ kN point loads at joints C and E act horizontally in the x$-$direction. List down zero forces member$/$s if there is any
