1. F₁ = 6 N, F₂ = 10 N. Sephetho sa divekthara tse pedi tsa matla ke…

Puisano
F_1x =F₁ Cos 60^o = (6)(0,5) = 3 N (e ntle hobane e ka lehlakoreng le letle la x)
F_2x =F₂ Cos 30^o = (10)(0,5√3) = 5√3 = (5)(1,372) = -8,66 N (e mpe hobane e ka lehlakoreng la x le mpe)
F_1y =F₁ sebe 60^o = (6)(0,5√3) = 3√3 = (3)(1,372) = 4,116 N (e ntle hobane e le ka lehlakoreng le letle la y)
F_2y =F₂ sebe 30^o = (10)(0,5) = -5 N (e mpe hobane e ka lehlakoreng le mpe la y)

F_x =F_1x - F_2x = 3 – 8,66 = -5,66 N
F_y =F_1y - F_2y  = 4,116 – 5 = -0,884 N

Vekthara e hlahang ke 5,7 N.

2. F₁ = 4 N, F₂ = 4 N, F₃ = 8 N. Sephetho sa divekthara tse tharo tsa matla ke…

Puisano
F_1x =F₁ Cos 60^o = (4)(0,5) = 2 N (e ntle hobane e ka lehlakoreng le letle la x)
F_2x = -4 N (e mpe hobane e ka lehlakoreng le lebe la x)
F_3x =F₃ Cos 60^o = (8)(0,5) = 4 N (e ntle hobane e ka lehlakoreng le letle la x)
F_1y =F₁ sebe 60^o = (4)(0,5√3) = 2√3 N (e ntle hobane e le ka lehlakoreng le letle la y)
F_2y = 0
F_3y =F₃ sebe 60^o = (8)(0,5√3) = -4√3 N (e mpe hobane e ka lehlakoreng le mpe la y)

F_x =F_1x - F_2x +F_3x = 2 – 4 + 4 = 2 N
F_y =F_1y +F_2y  - F_3y = 2√3 + 0 – 4√3 = -2√3 N

Vekthara e hlahang ke 4 N.
