Tom ntej no peb tuaj rau xam tus mechanical kom zoo dua ntawm ib tug lever. Ua li no, koj faib qhov kev ncua deb ntawm lub fulcrum, qhov taw tes ntawm lub zog pivots, mus rau lub zog thov los ntawm qhov kev ncua deb ntawm lub fulcrum mus rau lub zog tsis kam. Siv daim duab no, qhov no txhais tau tias faib qhov deb b los ntawm qhov deb a.

Kuj paub, dab tsi yog qhov zoo ntawm kev siv tshuab ntawm lub tshuab yooj yim?

Mechanical kom zoo dua yog ib qho kev ntsuas ntawm lub zog amplification tiav los ntawm kev siv lub cuab yeej, txhua yam ntaus ntawv los yog tshuab lawv. Cov cuab yeej khaws cia lub zog tawm tswv yim thiab tsuas yog ua lag luam tawm tsam tawm tsam kev txav mus los kom tau txais qhov xav tau amplification hauv qhov tso zis quab yuam.

Kuj Paub, dab tsi yog qhov zoo mechanical kom zoo dua? Qhov zoo tagnrho mechanical kom zoo dua sawv cev rau qhov kev hloov pauv ntawm lub zog tawm tswv yim uas yuav ua tiav los ntawm lub tshuab yog tias tsis muaj kev sib txhuam kom kov yeej. Qhov zoo tagnrho mechanical kom zoo dua yog ib txwm loj dua qhov tseeb mechanical kom zoo dua vim tias txhua lub tshuab yuav tsum kov yeej kev sib txhuam.

Nyob rau hauv no txoj kev, dab tsi yog lub mis rau zoo tagnrho mechanical kom zoo dua?

Yog hais tias cov pulleys no zoo tagnrho (frictionless thiab massless) lub mechanical kom zoo dua yog MAideal = 2. Qhov tseeb mechanical kom zoo dua yog qhov piv ntawm qhov tso zis quab yuam rau lub zog input. Cov zoo tagnrho txhua yam kom zoo dua yog mechanical kom zoo dua hauv ib zoo tagnrho ntiaj teb. Nws sib npaug ntawm qhov kev tawm tswv yim sib faib los ntawm qhov tso zis nrug.

Dab tsi yog units rau mechanical kom zoo dua?

Cov mechanical kom zoo dua ntawm lub tshuab yog qhov piv ntawm qhov load (qhov kev tiv thaiv kov yeej los ntawm lub tshuab) rau kev siv zog (lub zog siv). Tsis muaj unit rau mechanical zoo txij li thaum chav tsev rau ob qho tib si input thiab output rog tshem tawm.
