PROBLEM 2 A truss shown in Figure 2 is subject to 3 loads of P perpendicular to AH at joint B, D and F, and a downward P load at joint L. It is known that members BC, DE, FG are perpendicular to AH. Similarly, members IJ, KL and MN are perpendicular to HO. 2a) Identify ALL the zero-force members. {1.5 marks) 2b) Determine the force of members FH, HG, HI & HJ. State if the members are in tension or compression {7.5 + 1 marks 2c) [BONUS Determine the force of member DG by using maximum TWO (2) equations of equilibrium ONLY, provided reactions are found in advance. {1.5 marks) 2d) [BONUS) If load P at L is removed, identify the additional zero-force members. {0.5 marks) P 8 @ a = 8a Н.
