Consider the space truss represented schematically in Figure 1. It has 21 struts and a fixed support at “A”. At joint “G”, it is applied a force vector with a component of -20 N, along the x-axis, and a component of 10 N, along the y-axis, as shown in Figure 1. Using the method of joints, calculate the forces for the struts converging at joint “E”, i.e. the forces for struts “EA”, “EB”, “EF”, “EG”, “ED” and “EH” and specify if the struts are in tension or in compression.
