Imidwebo ye-metric yalandela uhlelo lokulinganisa metric, isebenzisa amamilimitha ngentambo yentambo nobubanzi. I-BSP Threads, ngakolunye uhlangothi, sebenzisa uhlelo lokulinganisa lwamapayipi eBrithani, ngesilinganiso sentambo esilinganiswe ngemicu nge-intshi ngayinye kanye nobubanzi obulinganiswe ngamasentimitha.
Q: Ngabe intambo ye-metric ingasetshenziswa ngokushintshana ngentambo ye-BSP?
A: Imicu ye-metric kanye nemicu ye-BSP ayiguquki ngenxa yezinhlelo zazo ezihlukile nemiklamo. Imicu ye-metric ine-pitch enhle kanye ne-angle yentambo ehlukile uma kuqhathaniswa nemicu ye-BSP. Ukuzama ukushintshana kwabo kungahle kube nomphumela wokuvuza okungafanele, ukuvuza, noma ukulimala kwezinto ezifakwe intambo.
Q: Ngabe zikhona izinhlangano ezilinganiselayo zentambo ye-metric nentambo ye-BSP?
A: Yebo, kunezinhlangano ezijwayelekile zentambo ye-metric nentambo ye-BSP. Inhlangano yamazwe omhlaba ye-Standard (ISO) isetha amazinga emicu ye-metric, ukuqinisekisa ukuhambisana kanye nokufana kuwo wonke amazwe. Ngemicu ye-BSP, isikhungo sezindinganiso zamaBrithani (BSI) sibhekele ukusungula nokugcina izindinganiso.
Q: Yiziphi izimboni ezisetshenziswa kakhulu intambo ye-metric?
A: Imicu ye-metric isetshenziswa kabanzi ezimbonini ezinjengezimoto, imishini kanye nezokukhiqiza. Bajwayele ukutholakala emazweni aseYurophu nawase-Asia lapho uhlelo lwe-metric luwuhlelo lokulinganisa olujwayelekile. Imicu ye-metric inikeza ukuxhumana okunembile futhi okuthembekile, kubenze balungele izinhlelo ezahlukahlukene.
Q: Ngabe kukhona izinzuzo zokusebenzisa intambo ye-BSP ngentambo ye-metric?
A: Imicu ye-BSP inezinzuzo kuzicelo ezithile. Zivame ukusetshenziswa kumapayipi kanye namasistimu we-hydraulic, ikakhulukazi emazweni alandela uhlelo lokulinganisa lwaseBrithani. Imicu ye-BSP inomklamo we-tatro, evumela ukuthi uphawu olunzima kanye nokuphikiswa okungcono ekuvuza ukuqhathaniswa nemicu ye-metric.
Q: Ingabe intambo ye-metric ingaguqulwa kalula?
A: Ukuguqula phakathi kwentambo ye-metric nentambo ye-BSP kudinga ukucatshangelwa ngokucophelela futhi kungenzeka kungafezwa kalula. Izinhlelo ezihlukile zokulinganisa, imicu yentambo, kanye nemibhobho kwenza ukuguqulwa okuqondile kuyinselele. Kwezinye izimo, ama-adaptha noma ukufakwa okunamathiselwe okuhambisanayo kungasetjenziswa ukuxhuma izingxenye ngezinhlobo ezahlukahlukene zentambo. Kodwa-ke, kunconywa ukusebenzisa uhlobo lwentambo efanelekile ukusebenza kahle nokuphepha.
