2. Kuyambitsa mankhwala
Pulley ndi lever yopunduka, yomwe ndi makina osavuta a gulu la lever ndipo imakhala ndi ntchito zambiri.M'dziko lathu kuyambira nthawi ya Warring States, pali mbiri ya pulley m'buku la "Mo Jing".Pulley yokhazikika yokhala ndi axis yokhazikika yapakati ndi ndodo yopunduka yofanana ndi mkono, yomwe imakhala yosavutikira komanso yosavutikira koma imatha kusintha njira yamphamvu.Pulley yomwe nsonga yapakati imayenda ndi kulemera kwake imatchedwa pulley yosuntha, yomwe imakhala yopunduka yosagwirizana ndi ndodo yamanja (chotchinga chopulumutsa ntchito), chomwe chingapulumutse theka la mphamvu, koma mtengo wowirikiza kawiri mtunda (pulley yosuntha imakwera n mamita. , ndipo mapeto aulere a chingwe amakwera mamita 2n , n≥0), ndipo sangathe kusintha njira ya mphamvu.Ziribe kanthu komwe kuwongolera mphamvu ya chingwe cha pulley kuli, mphamvu yomwe imagwiritsidwa ntchito kukweza chinthu cholemera ndi yofanana (mkono wa mphamvu ndi mkono wotsutsa ndizofanana komanso zofanana ndi utali wa pulley);chopulumutsa kwambiri ntchito ndi pamene mphamvu yolunjika ya nsonga ya pulley yosunthika imayimirira m'mwamba..
M'zochita, chiwerengero china cha ma pulleys osinthika ndi ma pulleys okhazikika nthawi zambiri amaphatikizidwa m'magulu osiyanasiyana a magulu a pulley.Gulu la pulley onse amapulumutsa khama ndikusintha njira ya mphamvu.Pulley yosiyanitsa (yomwe imadziwika kuti chain hoist) yomwe imagwiritsidwa ntchito m'mafakitale ndi gulu la pulley.Magulu a pulley amagwiritsidwa ntchito kwambiri mu cranes, hoists, elevators ndi makina ena.Pulley wawonekera mu mawonekedwe a mfundo za chidziwitso mu kalasi yachisanu ndi chimodzi ya kope la sayansi la People's Education Edition, ndi giredi 8 la Shanghai Jiaotong University (zonse zili m'buku limodzi), zomwe zimafuna kusiyanitsa pakati pa kupulumutsa ntchito, kusintha njira, ndi kujambula magulu a pulley.
