Calculate the force in member BG using a freebody diagram of the rigid member ABC. The force is positive if in tension, negative if in compression. E 10 F 10 G 12 10' 10 730 lb Answer: BG - i Ib

Question 4 (Type B): Determine the magnitudes of forces in members BF, DF, and DC using the method of section and identify whether they are in tension (T) or compression (C). A E B F₁ = 100 N 45° 2 m D F₂ = 50 N 2 m F 45°

Determine the force in each member of the truss shown. State whether each member is in tension orcompression and tabulate the results.

Question 1 Member ABC of negligible weight is supported by a pin and bracket at B and by an inextensible cord attached at A and C and passing over a frictionless pulley at D. For the loading shown and neglecting the size of the pulley, calculate the tension in the cord ,the horizontal and vertical reactions at point B.
