Tus fulcrum yog qhov taw tes ntawm lub nqaj pivots. Thaum ib qho kev siv zog siv rau ib qho kawg ntawm lub lever, ib qho load yog siv rau ntawm qhov kawg ntawm lub lever. … Levers cia siab rau lub zog rau lawv txoj haujlwm. Torque yog tus nqi zog uas yuav tsum tau ua kom ib qho khoom tig ib ncig ntawm nws axis (los yog pivot point).
Yim hu ua fulcrum?
Lub ntsiab lus ntawm fulcrum yog a pivot taw tes nyob ib ncig ntawm lub lever tig, los yog ib yam dab tsi uas ua lub luag haujlwm tseem ceeb hauv lossis nyob hauv nruab nrab ntawm qhov xwm txheej lossis kev ua ub no. Ib qho pivot point nyob ib ncig ntawm lub lever tig yog ib qho piv txwv ntawm fulcrum. Ib tug neeg nyob ib puag ncig uas txhua yam kev ua ub no yog ib qho piv txwv ntawm fulcrum. npe.

thawj chav kawm qib - lub fulcrum yog nyob rau hauv nruab nrab ntawm lub dag zog thiab lub load. Hom lever no muaj nyob rau hauv caj dab thaum tsa koj lub taub hau mus rau lub taub hau football. Lub caj dab cov leeg muab lub dag zog, lub caj dab yog lub fulcrum, thiab lub luj ntawm lub taub hau yog lub load.
Yuav ua li cas yog lub zog hauv physics?
Ib kauj ruam (/ˈliːvər/ los yog US: /ˈlɛvər/) yog ib lub tshuab yooj yim uas muaj cov nqaj lossis cov pas nrig sib txuas ntawm lub pob khawm ruaj khov, lossis fulcrum. Lub lever yog lub cev nruj uas muaj peev xwm tig tau ntawm qhov taw tes ntawm nws tus kheej. Raws li qhov chaw ntawm fulcrum, kev thauj khoom thiab kev siv zog, lub zog tau muab faib ua peb hom.
1st 2nd thiab 3rd chav levers yog dab tsi?
- thawj chav kawm levers muaj qhov fulcrum nyob nruab nrab. - Ob chav levers muaj covload nyob nruab nrab. - Qhov no txhais tau hais tias lub thauj khoom loj tuaj yeem txav tau nrog kev siv zog tsawg. - Chav kawm thib peb muaj kev siv zog hauv nruab nrab.
