Kesetimbangan Benda

α = 30° , β = 60°

Tinjau Sumbu - X
[tex] \sum{F_x} = 0 \\
T_2 \cos \beta - T_1 \cos \alpha = 0 \\
T_2 \cos 60^o = T_1 \cos 30^o \\
\frac12 T_2 = \frac12 \sqrt3 \ T_1 \\
T_2 = \sqrt3 \ T_1 \ ... (i) [/tex]

Tinjau Sumbu - Y
[tex] \sum{F_y} = 0 \\
T_2 \sin \beta + T_1 \sin \alpha - w = 0 \\
(\sqrt3 \ T_1) \sin 60^o + T_1 \sin 30^o = 40 \\
\frac32 T_1 + \frac12 T_1 = 40 \\
2T_1 = 40 \\
T_1 = 20 \ N \\ \\
T_2 = T_1 \sqrt3 \\
T_2 = 20 \sqrt3 \ N[/tex]
