Dziwani zigawo za vekitala

Mavuto othetsedwa mu mavekitala - dziwani zigawo za mavekitala

1. Mphamvu ya 20 Newton imapanga ngodya ya 30 o ndi x-axis. Pezani zigawo zonse ziwiri za x ndi y za mphamvuyo.

Kuthetsa mavuto a mavekitala - kudziwa zigawo za mavekitala 1Anakonza

F x = F cos 30 o = (20)(cos 30 o ) = (20)(0.5 √ 3 ) = 10 √ 3 Ma Newton

F y = F tchimo 30 o = (20)(tchimo 30 o ) = (20)(0.5) = Newtons 10

2. F 1 = 20 Newton amapanga ngodya ya 30 o ndi y axis ndipo F 2 = 30 Newton amapanga ngodya ya 60 o ndi -x axis. Pezani zigawo zonse ziwiri za x ndi y za F 1 ndi F 2.

Kuthetsa mavuto a mavekitala - kudziwa zigawo za mavekitala 2Anakonza

F 1x = F 1 cos 60 o = (20)(cos 60 o ) = (20)(0.5) = -10 Newtons (negative chifukwa ili ndi njira yofanana ndi -x axis)

F 2x = F 2 cos 60 o = (30)(cos 60 o ) = (30)(0.5) = -15 Newtons (negative chifukwa ili ndi njira yofanana ndi -x axis)

F1y =F1 tchimo 60o = (20)(chimo 60o) = (20)(0.5√3= = 10√3 Newton (yabwino chifukwa ili ndi mbali yofanana ndi y axis)

F2y =F2 tchimo 60o = (30)(chimo 60o) = (30)(0.5√3) = -15√3 Newton (yoipa chifukwa ili ndi njira yofanana ndi -y axis)

3. F 1 = 2 N, F 2 = 4 N, F 3 = 6 N. Pezani zigawo zonse ziwiri za x ndi y za F 1 , F 2 ndi F 3!

Kuthetsa mavuto a mavekitala - kudziwa zigawo za mavekitala 3Anakonza

F 1x = F 1 cos 60 o = (2)(cos 60 o ) = (2)(0.5) = 1 Newtons (zabwino chifukwa zili ndi mbali imodzi ndi x axis)

F2x =F2 cos 30o = (4)(cos 30o) = (4)(0.5√3) = -2√3 Newton (yoipa chifukwa ili ndi njira yomweyo ndi mzere wa -x)

F 3x = F 3 cos 60 o = (6)(cos 60 o ) = (6)(0.5) = 3 Newtons (zabwino chifukwa zili ndi mbali imodzi ndi x axis)

F1y =F1 tchimo 60o = (2)(chimo 60o) = (2)(0.5√3) = √3 Newton (yabwino chifukwa ili ndi mbali yofanana ndi y axis)

F 2 y = F 2 sin 3 0 o = (4)(sin 30 o ) = (4)(0.5) = 2 Newtons (zabwino chifukwa zili ndi mbali yomweyo ndi y axis)

F3y =F3 tchimo 60o = (6)(chimo 60o) = (6)(0.5√3) = -3√3 Newton (yoipa chifukwa ili ndi njira yomweyo ndi -y axis)
