Isibonelo sombuzo wokunquma i-vector ephumelayo kusetshenziswa ama-vector ezingxenye

2 Izibonelo zemibuzo yokunquma i-vector ephumelayo kusetshenziswa ama-vector ezingxenye

I-1. F₁ = 6 N, F₂ = 10 N. Umphumela wamavektha amabili amandla u…

Ingxoxo
F_1x =F₁ ibe 60^o = (6)(0,5) = 3 N (enhle ngoba isendleleni elungile x)
F_2x =F₂ ibe 30^o = (10)(0,5√3) = 5√3 = (5)(1,372) = -8,66 N (engemihle ngoba isendleleni engemihle x)
F_1y =F₁ ngaphandle 60^o = (6)(0,5√3) = 3√3 = (3)(1,372) = 4,116 N (enhle ngoba isendleleni enhle ka-y)
F_2y =F₂ ngaphandle 30^o = (10)(0,5) = -5 N (engemihle ngoba isendleleni engemihle ka-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

Ivektha ephumelayo ingu-5,7 N.

I-2. F₁ = 4 N, F₂ = 4 N, F₃ = 8 N. Umphumela wamavektha amathathu amandla…

F_1x =F₁ ibe 60^o = (4)(0,5) = 2 N (enhle ngoba isendleleni elungile x)
F_2x = -4 N (i-negative ngoba isendleleni engemihle x)
F_3x =F₃ ibe 60^o = (8)(0,5) = 4 N (enhle ngoba isendleleni elungile x)
F_1y =F₁ ngaphandle 60^o = (4)(0,5√3) = 2√3 N (enhle ngoba isendleleni enhle ka-y)
F_2y = 0
F_3y =F₃ ngaphandle 60^o = (8)(0,5√3) = -4√3 N (engemihle ngoba isendleleni engemihle ka-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

Ivektha ephumelayo ingu-4 N.

Imibuzo mayelana nokunquma i-vector ephumelayo kusetshenziswa ama-vector ezingxenye

I-1. F₁ = 6 N, F₂ = 12 N. Umphumela wamavektha amabili amandla u…
I-2. F₁ = 10 N, F₂ = 10 N, F₃ = 15 N. Umphumela wamavektha amathathu amandla…
