QUESTION 4 In the structure below, member AB is attached to the wall with a fixed support at A and is attached to member BC with a fixed support at B. Force F has a value of 58 lb. Force G has a value of 53 lb. Force H has a value of 55 lb. What is the magnitude of the total reaction force that the ground provides at fixed support A in lb? 1.5ft A H 3ft B F 2ft 40°

)Use the method of MEMBERS to determine the true magnitude and direction of the forces in members1 and 2 of the frame shown below in Fig 3.2.

Q1: - For the frame shown in figure 1 below is subjected to two forces ( P=20 kN and Q=30 kN). Neglecting the weights of the bars, determine all forces that acting on each of the members. Use the two-force principle wherever applicable. 2 m 2 m A 60° D 60° 4 m 2 m 4 m

1)→ In the figure-below, find-the-forces-in-members AD, ED, and AB.-Can-the-forces-in-all-the- members of this-truss be found-from-statics equations alone? Why-or-why not? 50 lb 2 ft F G -3 ft- E A 3 ft. D -3 ft- B 100 lb 80 lb с
