Question 1 (50 marks) a) Identify all zero-force members in the truss. [10 marks] b) Using the method of sections, compute the forces in the members BC, BF, EI and EF (identified by x in the diagram). You can use your answer from part a) where applicable. [40 marks] Assume P= (5+0.Y) kN and Q = = (3+0.Y) [kN] where Y=the last digit of your student number.
