10N E 30N A 5m N ----- Z+ H Figure 1 B G |C 4m 3m Y

Hello this is a practice exam paper question could you please help me answer it.

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 30 N, along the x-axis, and a component
of 10 N, 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.
