Txij thaum lub sijhawm Roman faj tim teb chaws, qhov hnyav npib kub thiab nyiaj tau ua tiav siv qee hom kev ntsuas. Muaj ntau hom nplai uas tau siv los ntsuas qhov hnyav ntawm cov npib, suav nrog kev sib npaug ntawm caj npab sib npaug, cov nplai steelyard (ib hom kev sib npaug ntawm caj npab sib npaug), hnab tshos nplai, thiab cov nplais pob zeb sib npaug.

Sib npaug ntawm caj npab ntsuas uas tau siv rau kev hnyav nyiaj tau tsim kom raug thiab me me kom thauj los ntawm ib qho mus rau lwm qhov. Cov nplai muaj lawv tus kheej haum ntoo lossis hlau ntim. Txog thaum xyoo 1700s, cov nplai tau tsim los nrog kev txhim kho qhov tseeb thiab rhiab heev. Qhov no tau ua tiav los ntawm kev ua kom cov nplais sib zog, me dua, thiab ua nrog cov pob khawm zoo dua. Lub hnab tshos nplai tau tsim nyob rau xyoo 1770, uas muaj qhov sib npaug ntawm caj npab me me uas nyob hauv ib lub thawv me me. Qhov ntsuas tau zoo rau ntsuas me me. Rocker balance scales tau tsim nyob rau hauv lub xyoo pua puv 19, thiab qhov hnyav ntawm lub npib yuav tsum muaj tseeb nyob rau hauv kev txiav txim rau cov nplais kom sib npaug. Qhov ntsuas no kuj siv tau los ntsuas txoj kab uas hla thiab thickness ntawm ib npib.

Postal Scales

Cov nplai tau siv los ntsuas qhov hnyav ntawm cov ntawv thiab lwm cov pob me me los txiav txim seb tus nqi xa ntawv xav tau.

Analytical Scales

Kev tshawb fawb tau nce mus deb txaus los ntawm lub xyoo pua 18th los lav qhov xav tau rau cov ntsuas qhov tseeb thiab rhiab heev. Cov kws kho mob, kws muag tshuaj thiab kws tshuaj siv tshuaj ntsuam xyuas, uas muaj cov kab nruab nrab me me thiab cov lauj kaub me me uas ua los ntawm iav lossis tooj dag. Cov nplai no feem ntau tau ua rau hauv ib lub thawv, nrog rau txhua qhov kev ceev faj kom yooj yim rau kev sib txhuam ntawm lub pob khawm, pab ua kom cov nplais qhov tseeb. Ib qib thiab cov ntsia hlau tau siv los kho thiab kho cov nplai thaum xav tau.

Sib npaug ntawm caj npab ntsuas tau siv ntau txhiab xyoo, vim lawv yog hom kev ntsuas yooj yim tshaj plaws. Cov qauv tsim yooj yim pib nrog ib lub nqaj uas sib npaug ntawm nws qhov chaw nruab nrab ntawm lub hinged teeb ntawm txoj cai kaum rau kab. Lub ntsiab lus no hu ua fulcrum. Qhov sib npaug ntawm qhov hnyav yog raug tshem tawm ntawm txhua qhov kawg ntawm kab teeb. Cov lauj kaub kuj yog qhov sib npaug ntawm qhov sib npaug ntawm qhov fulcrum, uas yog qhov chaw ntawm lub nqaj nruab nrab ntawm lub ntiajteb txawj nqus nyob.

Yog li, txhawm rau ntsuas ib yam dab tsi, ib qho khoom raug muab tso rau hauv ib lub lauj kaub thiab sib txawv ntawm qhov hnyav ntxiv rau lwm lub lauj kaub kom txog thaum lub nqaj sib npaug dua, txhais tau tias nws yog kab rov tav. Tom qab ntawd cov khoom hnyav ntxiv ua ke los txiav txim siab tag nrho qhov hnyav ntawm qhov khoom. Muaj ob peb yam uas yuav cuam tshuam txog qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas li cas. Tus nqi ntawm kev sib txhuam ntawm lub pob khawm tuaj yeem ua qhov sib txawv thiab yog li tuaj yeem ua rau tag nrho qhov loj ntawm qhov ntsuas nws tus kheej.

Tej yam zoo li cov lauj kaub uas ploj lawm, qhov sib npaug ntawm qhov hnyav, lossis xeb tuaj yeem txo qis cov nplais qhov tseem ceeb.

Tsis tas li ntawd, cov nplais qub txeeg qub teg nce thiab txo tus nqi raws li cov ntaub ntawv uas lawv tau tsim tawm. Cov nplais ua los ntawm cov hlau muaj txiaj ntsig zoo li nyiaj thiab kub ib txwm yuav muaj txiaj ntsig ntau dua li cov uas ua los ntawm tooj dag lossis tooj liab, ua tsaug rau cov hlau lub hauv paus tus nqi. Yog li, koj tuaj yeem muaj ob qhov kev ntsuas tam sim no ntawm cov qauv zoo sib xws muag rau tus nqi sib txawv heev.
