Question 1: (20 marks) A cantilever truss structure is shown in Figure 1. A point load P-10 kN is acting at joint B and point loads 3 kN are acting at joints A, D and F. Consider points G and F have roller and pin supports, respectively. (a) State whether the truss is statically determinate or indeterminate. Find whether the truss is stable or unstable. (b) Find the reactions at all supports; (2 marks) (6 marks) (c) Use the method of section to determine the forces in members DF, EF and EG. State if the members are in tension or compression.
