tolong bantuu model soal ini,(:

Komponen Y
F1y = 30 sin 30
F1y = 30 × 1/2 = 15
F2y = 30 sin 30 = 15
F2y = 30 sin 0 = 0
Fy= 15+15+0=30
Komponen X
F1x = 30 cos 30
F1x = 30 × 1/3√3 = -10√3 (kearah sb -x)
F2x = 30 cos 30 = 10√3
F3x = 40 cos 0
F3x = 40 × 1 = 40
Fx = -10√3+10√3+40 = 40
Ftot = √Vx²+Vy²
Ftot = √40²+30² = √1600+900 =√2500
