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 40kg. Answer: b) Determine the largest mass of the suspended block so that the force in any member does not exceed 30kN (T) or 25kN (C). Answer: m= Mg (8 marks)
