Ulamuliro wa golide wa makina.

Ngakhale m'nthaŵi zakale, pamene njira zosavuta (malo, chiwindi, chipata, ndi zina zotere) zinagwiritsidwa ntchito, gawo lopambana la makinawa linapezeka. Zinaoneka kuti kayendetsedwe kake ka njira zosavuta kogwirizana ndi mphamvu zomwe makina amapanga. Tiyenera kukumbukira kuti chiŵerengero cha kayendetsedwe ka mapeto awiri a njira yosavuta imene mphamvu zimagwiritsidwira ntchito nthawi zonse ndilo kusiyana kwa chiŵerengero cha mphamvu zomwe zimagwiritsidwa ntchito kumapeto.

Mphamvu yomwe imakhudza dzanja lamanja la nkhwangwa ndi nthawi yochepa kuposa mphamvu yomwe imagwira kumanzere. Choncho, kuthamangitsidwa kwa mkono wamanja (s2) ndi nthawi yochuluka kusiyana ndi kusamuka kwa mkono wamanzere (s1).

Tiyerekeze kuti, pofuna kuti muyambe kuyima, mphamvu F2 iyenera kukhala yochepa kuposa mphamvu F1. Pachifukwa ichi, pamene chiwindi chimasinthasintha, kayendetsedwe ka s2 kotsirizira kawiri kakhala kakang'ono kwambiri kusiyana ndi kayendetsedwe kake kotsiriza. Ngati chipikacho ndi chachiwiri, ndiye kuti mgwirizano wofanana pakati pa mphamvu zomwe zimagwiritsidwa ntchito ku zingwe zomwe zimadulidwa pazitsulo ziwirizo ndizoziika mu malo ofanana ndi zenizeni, ndipo kusuntha kwa chingwe kumatha pamene bwalo likuzungulira. Popeza kufunika kwa makonzedwe ameneŵa sikungakhale kovuta kwambiri, kunatchulidwa bwino kwambiri: "malamulo a golide".

Pogwiritsira ntchito chidziwitso chomwe chinayambitsidwa, dongosolo la golide lopangidwa ndi golide lingathe kuwonetsedwa motere:

S1 / s2 = F2 / F1

Kapena s1 * F1 = s2 * F2.

Pambuyo pake, mitundu ya kayendedwe kamene ndi makina omwe amagwiritsidwa ntchito mu makina anayamba pang'onopang'ono. Zinaoneka kuti malamulo a golide samagwiritsabe ntchito mosavuta. Komabe, makina a mitundu ndi mitundu ya kayendedwe kanakhala kovuta kwambiri, makina opangira golide anakhalanso ovuta kwambiri. Choncho, poyang'anira, milandu inakhala yovuta kwambiri. Tiyenera kudziŵa kuti dongosolo la golide lopangidwa ndi golide linasanduka maziko a malingaliro osiyanasiyana pa mphamvu ndi ntchito. Komanso, lamulo ili ndilo loyamba, lokhazikitsidwa bwino la lamulo la kusunga mphamvu, zomwe zimakhala zogwirizana ndi zochitika zonse zachirengedwe.

Kugwiritsa ntchito "malamulo a golidi"

Lamuloli lidalibe lokha pokhapokha ngati pali makina ophweka (kapena ndi zochepa). Mwachitsanzo, pamene zibowo ziwiri zimayendayenda, malekezero a zingwe amasunthira ku maulendo s1 ndi s2, omwe amavulaza pazitsulo za radii r1 ndi r2 ndipo, zowonjezera, amamangiriza palimodzi. Maulendowa ndi ofanana ndi radii r1 / r2 = s1 / s2.

Choncho, kuti lamulo la golidi likhale loyenerera pazitsulo ziwiri, izi ziyenera kukhazikitsidwa: F1 / F2 = r2 / r1.

Pankhaniyi, mphamvu F1 ndi F2 zidzafanana. Chifukwa chake, makina ayenera kuchita zoyendayenda, kapena apumule. Komabe, pofuna kuyendetsa gawo limodzi, chiwerengerocho chiyenera kusokonezeka. Kuti tichite izi, tifunika kuwonjezera mphamvu zamphamvu, kunena, F1. Gulu lomwe lidzatuluka mu thupi lidzafulumizitsidwa.

Ndalama ya dziko lonse

Ndalama za dziko ndi ndalama zomwe zimaperekedwa ndi mabanki a anthu kapena boma kuti cholinga chake chigwiritsidwe ntchito m'deralo kapena kunja. Zimagwiritsidwa ntchito pokhapokha kusintha kwa zachuma, komanso m'madera ena, omwe amachokera kuwerengera ndalama.

Kusonkhanitsa kuchokera ku kugulitsa kwa ndalama

Funso loyambitsa malipiro a mtundu wa ntchito monga kugulitsa ndalama, mwachitsulo chomwe chimabweretsa m'madera ena, chikhoza kufanizitsidwa ndi chisankho cha ulamuliro wapamwamba komanso chiyambi cha ntchito ya parliament yatsopano. Chifukwa cha malingaliro ambiri a akatswiri pankhaniyi, National Bank ikuyenera kugwira ntchito yolongosola ntchito pakati pa anthu a dzikoli. Motero, adzatha kufotokozera anthu malamulo ndi malingaliro ena omwe angakhale othandiza kwa anthu onse m'tsogolomu.
