F1 = 100 N, θ1 = 30° F2 = 150 N, θ2 = 60°
Find the resultant force components.
F = 200 N, acting at point A (2, 3, 4) Point O (0, 0, 0) F1 = 100 N, θ1 = 30° F2
F1x = 100 cos(30°) = 86.60 N F1y = 100 sin(30°) = 50 N F2x = 150 cos(60°) = 75 N F2y = 150 sin(60°) = 129.90 N F1 = 100 N
Calculate the moment of the force about point O. acting at point A (2
