Figure 1 shows a load suspended from the truss. The truss is supported by pin-type support at $$G$$ and roller-type support at $$A$$. a) By using a joint method, determine the force in each truss member and state if the members are in tension or compression. Assume the load has a mass of $$40\mathrm{kg}$$. Answer: b) Determine the largest mass of the suspended block so that the force in any member does not exceed $$30\mathrm{kN}$$ (T) or $$25\mathrm{kN}$$ (C). Answer: $$m=$$ Mg (8 marks)
