Dziwani zotsatira za mavekitala awiri pogwiritsa ntchito zigawo za vekitala

Mavuto othetsedwa mu ma vector - zotsatira za mavekitala awiri pogwiritsa ntchito zigawo za vekitala

1. F₁ = 6 N, F₂ = 10 N. Dziwani vekitala yotsatira.

Anakonza

F_1x =F₁ 60^o = (6)(0.5) = 3 N (zabwino chifukwa zili ndi njira yofanana ndi x axis)

F_2x =F₂ 30^o = (10)(0.5√3) = 5√3 = (5)(1.372) = -8.66 N (yoipa chifukwa ili ndi njira yofanana ndi -x axis)

F_1y =F₁ tchimo 60^o = (6)(0.5√3) = 3√3 = (3)(1.372) = 4.116 N (zabwino chifukwa zili ndi njira yofanana ndi y axis)

F_2y =F₂ tchimo 30^o = (10)(0.5) = -5 N (yoipa chifukwa ili ndi njira yofanana ndi -y axis)

F_x =F_1x - F_2x = 3 – 8.66 = -5.66 N

F_y =F_1y - F_2y = 4.116 – 5 = -0.884 N

Zotsatira za mphamvu ziwirizi ndi 5.7 N.

2. F₁ = 4 N, F₂ = 4 N, F₃ = 8 N. Dziwani vekitala yotsatira.

Anakonza

F_1x =F₁ 60^o = (4)(0.5) = 2 N (zabwino chifukwa zili ndi njira yofanana ndi x axis)

F_2x = -4 N (yoipa chifukwa ili ndi njira yofanana ndi -x axis)

F_3x =F₃ 60^o = (8)(0.5) = 4 N (zabwino chifukwa zili ndi njira yofanana ndi x axis)

F_1y =F₁ tchimo 60^o = (4)(0.5√3) = 2√3 N (zabwino chifukwa zili ndi njira yofanana ndi y axis)

F_2y = 0

F_3y =F₃ tchimo 60^o = (8)(0.5√3) = -4√3 N (yoipa) chifukwa ili ndi njira yofanana ndi -y axis)

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

Zotsatira za mphamvu zitatuzi ndi 5.7 N.
