F1:6N
F2:5N
α:60°
kita hitung dulu besar komponennya menggunakan rumus:
F1=6
α=60°
F1x=6 cos 60°
F1x=6 .0,5
F1x=3
F1y=6 sin 60
F1y=6.1/2√3
F1y=3√3
F2=5
α=60°
F2x=5os 60
F2x=5.0,5
F2x=2,5
F2y=5sin60
F2y=5.1/2√3
F2y=2,5√3
Rx=F1x+F2x
Rx=3+2,5
Rx=5.5
Ry=3√3+2,5√3
Ry=5,5√3
R=√Rx²+Ry²
R=√(5,5²+5,5√3²)
R=√(30,25+90,75)
R=√121
R=11
