Isikhungo sesisindo

I-Pengertian
Umzimba oqinile ubhekwa njengowakhiwe yizinhlayiya eziningi, kanti isisindo sento siyisamba sesisindo senhlayiya ngayinye eyakha into. Isikhungo sesisindo siyindawo entweni lapho isisindo sazo zonke izinhlayiya ezakha into sibhekwa njengesigxile khona kuleyo ndawo.

Ifomula
Wonke umzimba oqinile ucatshangwa ukuthi wakhiwe yizinhlayiya eziningi, ngayinye eqhelelene kakhulu nomunye. Kodwa-ke, ukuze kube lula ukuthola ifomula yokunquma isikhungo sesisindo, kwenziwa lula ngokuthatha ukuthi umzimba oqinile uqukethe izinhlayiya ezimbili kuphela. Lezi zinhlayiya ezimbili zingabizwa ngokuthi uhlelo lomzimba oluqinile.

m₁ = isisindo sezinhlayiya 1, m₂ = isisindo sezinhlayiya 2. Zombili izinhlayiya ziku-x-axis. Inhlayiya 1 ikude x1 ukusuka ku-y-axis kanti inhlayiya 2 ikude x₂ kusukela ku-y-axis. Isikhungo sobuningi sifinyeziwe ngokuthi i-PM. Zombili izinhlayiya zitholakala ku-x-axis, ngakho-ke isikhungo sobunzima bezinhlayiya zombili sibhalwe ngokuthi x_PM.
m = m₁ +m₂ = isisindo esiphelele sezinhlayiya zombili. Uma m₁ +m₂ = m khona-ke isikhungo sobunzima siphakathi nendawo yezinhlayiya ezimbili. Ngokwezibalo, i-equation ingashintshwa ibe yi:
Uma u-m1 > m2 khona-ke isikhungo siseduze no-m1. Ngokuphambene nalokho, uma u-m2 > m1 khona-ke isikhungo siseduze no-m2. Isibalo esingenhla sisebenza kuphela kubukhulu obulodwa, lapho inhlayiya ikwenye yama-axes e-coordinate (i-x-axis).
Uma izinhlayiya ezimbili zisendizeni (ubukhulu obu-2) khona-ke singangeza isikhungo se-mass equation se-coordinate ka-y.
Ifomula engenhla inqunyelwe ezinhlayiyeni ezimbili. Uma kunezinhlayiya ezengeziwe, singayandisa ifomula.
Ifomula ye-x coordinate:
Ifomula ye-coordinate ka-y:
Ifomula ye-z coordinate:
Uma izinhlayiya zitholakala endizeni (ubukhulu obubili) khona-ke isikhungo sento siphakathi kuka-x_PM kanye no-y_PMNgakolunye uhlangothi, uma izinhlayiya zitholakala esikhaleni (ubukhulu obuthathu), khona-ke isikhungo sesisindo sento siphakathi kuka-x_PM, futhi_PM kanye no-z_PM.
