Zimango zamagalimoto: njira zosavuta zamagalimoto

Makina osavuta ndi zida zamakina zomwe zimathandiza kukonza moyo watsiku ndi tsiku wa anthu powalola kuti azigwira ntchito mwachangu, mosavuta komanso moyenera. Makina osavuta amatengedwa kuti ndi njira zoyambira zomwe zimapanga makina onse ovuta. Mitundu isanu ndi umodzi yofunikira yamakina osavuta: pulley, screw, ndege yokhotakhota, gudumu ndi exle, m'mphepete ndi lever. Pamene anthu akugwira ntchito, monga kugwiritsira ntchito mphamvu kusuntha zinthu zolemera, makina osavuta amapangitsa ntchito zofala zimenezi kukhala zosavuta. Makina angapo osavuta akamagwira ntchito limodzi, amapanga makina ophatikiza. Chitsanzo cha izi chingakhale makina a pulley omwe ali ndi ma pulleys awiri kapena kuposerapo. Makina akapangidwa ndi makina ambiri osavuta komanso ophatikizika, amapanga makina ovuta. Chitsanzo chabwino cha makina ovuta ndi galimoto. Magalimoto ali ndi njira zambiri zosiyana - chiwongolerocho chimakhala ndi gudumu ndi chitsulo, ndipo kusuntha kwa magalimoto m'magalimoto oyendetsa basi kumayendetsedwa ndi levers.
