The space truss has roller supports at B$,$ C$,$ and D$,$ and supports a vertical load at A$.$ Assume $3$ sig fig precision for all measurements in the picture. Recall

that a roller support only has one reaction force that is normal to the surface $($the X$-$z plane is the surface in this case$).$ For this problem ONLY, you may use

Matlab$/$Octave to solve the math. Just be sure to include$/$attach the code that you use.

a$.$ Solve for the reactions at the roller supports.

b$.$ Solve for the axial forces in members CA$,$ CB and CD$.$ Be sure to label the axial forces as tension $(T)$ or compression $($C$).$
