Consider the space truss represented schematically in Figure $1.$ It has

$21$ struts and a fixed support at $"C".$ At joint $"E",$ it is applied a force

vector with a component of $30N,$ along the $x-$axis, and a component

of $10N,$ along the negative $y-$axis, as shown in Figure $1.$ Using the

method of joints, calculate the forces for the struts converging at joint

$"G",$ i$.$e$.$ the forces for struts $"GB","GC","$GD$","$GE$","$GF$"$ and $"$GH$"$

and specify if the struts are in tension or in compression. $($Your

submission must include the Free Body Diagram $($FBD$)$ of each joint

and the application of the equilibrium equations for the

corresponding FBD$).$
