P = 5kN, a = 3 ; Need help ASAP, appreciate it
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 Pat L is removed, identify the additional zero-force members. {0.5 marks 8@. a = 8a Р H Р 1 P K G 4 @ 0.5a = 2a M B A C E L N Р 1.25a 1.25a За 1.25a 1.25a Figure 2
