Piv txwv ntawm Compound Pulleys : A compound pulley yog kev sib xyaw ua ke ntawm qhov yooj yim thiab txav tau rubey . Nws yog qee zaum hu ua kev sib xyaw ua ke rubey . Nws tau tsim los ua kom siv zog tsawg dua ib nrab ntawm qhov hnyav ntawm lub nra. Nws yog ib qho ntawm cov chaw tsim kho uas cranes nqa hnyav hlau thiab cov khoom ua vaj tse.
Ib yam li ntawd, nws raug nug, ua li cas lub tshuab rub tawm ua haujlwm?
A rubey yog hlua qhwv ib lub log. Nws hloov txoj kev quab yuam. Ib qho yooj yim compound pulley muaj txoj hlua txuas rau qhov chaw nyob ruaj khov nyob ib puag ncig ib lub log thiab tom qab ntawd nyob ib ncig ntawm lub log thib ob. Rub rau ntawm txoj hlua rub ob lub log los ze zog ua ke.
Ib qho ntxiv, ob yam zoo ntawm kev siv cov khoom siv sib dhos yog dab tsi? Qhov ntau rubey system muaj peev xwm sib zog ua kom muaj zog thiab rub lub zog ntawm lub winch, txo qhov kev nyuab siab ntawm lub winch thiab cov khoom raug rub. Xws li ib qho system tuaj yeem pom ntawm ntau qhov hnyav nqa cranes thiab overhead winching tshuab. Lub thaiv thiab tackle kuj yog ib hom compound lawv.
Hauv qhov no, ob hom pulleys yog dab tsi?
Muaj ob lub ntsiab hom pulleys : 1. Ib qho tsau rubey hloov cov kev taw qhia ntawm lub zog, lossis thawb lossis rub, uas txav lub nra. Tsau cov hlua feem ntau siv rau ntawm tus chij.
Qib 3 Cov Tshuab Yooj Yim
- log thiab hlua.
- tsau thiab movable.
- sib xyaw thiab thaiv thiab sib tw.
Yuav ua li cas yog ib co piv txwv ntawm pulleys nyob ib ncig ntawm lub tsev?
