Mota mechanics: nzira dzakareruka mumotokari

Michina yakapfava zvinhu zvemuchina zvemunhu zvinobatsira kuvandudza hupenyu hwezuva nezuva hwevanhu nekuvabvumira kushanda nekukurumidza, nyore, uye nemazvo. Michina yakapfava inoonekwa senzira dzekutanga dzinoumba michina yese yakaoma. Nhanhatu mhando dzemakina akareruka: pulley, screw, yakarerekera ndege, vhiri uye axle, mupendero uye lever. Kana vanhu vachiita basa, rakadai sokushandisa simba kufambisa zvinhu zvinorema, michina iri nyore inoita kuti aya mabasa akajairika ave nyore. Kana michina yakati wandei ichishanda pamwechete, inogadzira muchina unoumbwa. Muenzaniso weizvi ungave pulley system ine maviri kana anopfuura pulleys. Kana muchina wakagadzirwa nemichina yakawanda yakapfava uye yakasanganiswa, vanogadzira muchina wakaoma kunzwisisa. Muenzaniso wakanakisisa wemuchina wakaoma imotokari. Mota dzine akawanda akapatsanurwa masisitimu akareruka - vhiri rekutungamirira rine vhiri uye axle, uye giya rekuchinja mumotokari dzine otomatiki transmission inodzorwa nemalevers.
