F₁ F2 Ф A L1 B N C L3 D h y F3 Find the equivalent resultant force and couple moment of the force system about point A, given: F₁ = 190 lbs, F2 = 120 lbs, F3 = 90 lbs, L₁ = 4 ft, L₂ = 6ft, L3 = 5ft, 8 = 40°, x,y,h = 5,12,13, respectively The magnitude of resultant force, FR is: FR= Number lbs The angle of the resultant force as measured from the positive x-axis is: (Note, in quadrant 1 or 2, the angle should be beween 0 and 180 degrees, while in quadrant 3 or 4, the angle should be between 0 and -180 degrees). OR = Number The resultant moment about point A is: MRA = Number lb-ft
