A space truss structure shown in the figure below can

be considered as a system of concurrent forces in $3$D$.$

The figure below shows the four forces $T_A,T_B,T_C$ and $T_D.$

Force $T_c$ is located on the $x-z$ plane, Force $T_{}$ has

two projection angles: $=60$ is the projection angle of the

force $T_B$ to the $x-y$ plane, and $=30$ is the angle between

the projected force and $x-$axis. Force $T_0$ actr along

line $OD,$ and force $T_A$ is located as shown in the figure

below. If it is known that force $T_B$ is $100$ kips and the

system of forces is in equilibrivm condition, calculate the

magnitude of the forces $T_A,T_C,$ and $T_D.$
