Amaqhosha, ekuqaleni isetyenziselwa ikhonkco lempahla, nangona kunjalo, iphuhliswe ukuza kuthi ga namhlanje, amaqhosha ukongeza kuwona msebenzi wekhonkco wentsusa, kodwa wandisa ukuhlobisa kunye nokuhombisa umsebenzi.Ngokutsho kophando, imbali yamaqhosha aseTshayina inokulandelwa emva kweminyaka eyi-1800 edlulileyo.Izinto eziphambili zamaqhosha okuqala ngamatye, iinkuni, iingubo kunye nokunye.Ngenkulungwane ye-13, abantu belizwekazi laseYurophu baqalisa ukusebenzisa amaqhosha.Emva kweRevolution yemizi-mveliso ngenkulungwane ye-18, amaqhosha entsimbi aqalisa ukuthandwa.
Ke, alinganiswa njani amaqhosha?Iyunithi yeqhosha ibizwa ngokuba nguL, unobumba wokuqala womgca.
Yintoni iLigne?
ILigne yiyunithi yobude ethathwe kwigama lesiFrentshi lomgca.I-Ligne yaqala ukusetyenziswa ngabavelisi beqhosha baseJamani ngenkulungwane ye-9 ukumisela ubungakanani bamaqhosha, kwaye ekugqibeleni yaba yiyunithi eqhelekileyo yokulinganisa amaqhosha ngenkulungwane ye-18.
Ukuguqulwa kwemilinganiselo
Abantu abangaqhelananga nobungakanani beqhosha L banokuliguqula libe zii-intshi okanye iisentimitha.
I-1 L = 0,635 mm
1 mm = 1/25"
Ngokomzekelo, ukuba ububanzi beqhosha bu-18mm, ubukhulu beqhosha bungabalwa ukuba bube yi-28L (18/0.635 = 28.34).
Oku kulandelayo yitafile yokuguqula ubungakanani obuqhelekileyo.
Ingcebiso:
1, Idayamitha yeqhosha: ubuninzi bangaphandle bedayamitha yeqhosha.
2 、 Buckle idayamitha: Ukulinganisa i-diameter yangaphakathi.
Nangona inkqubo yokulinganisa yeiqhoshaubungakanani izandi ezintsokothileyo ekuqaleni, ngokwenene kulula kakhulu ukubala.DUMBAuziphuamaqhosha okubonelela ngobungakanani obahlukeneyo kunye nemathiriyeli, ukuba ufuna, ungabonisana ngokweenkcukacha.
