Two rods and one cable are attached to the support at O. If two of the forces are as shown, determine the magnitude and the direction of the third force F so that the resultant of the three forces is vertically downward with a magnitude of 1200 lb. 1000 lb 45 30 500 lb x Question 2 Use triangle or parallelogram method to solve this question: The two forces shown below act at point A of the bent bar. Determine the resultant R of the two forces. (1 kips = 1000 lb) F = 3 kips 30 45 A L- F= 7 kips
