Ukusetyenziswa okuninzi koMlawuli oyiSiseko

Abalawuli zizixhobo eziluncedo, kodwa ngamanye amaxesha asiyithathi lula into abanokuyenza. Lo mtya womthi, iplastiki, okanye intsimbi ayingowokuzoba imigca ethe tye. Inokukunceda ukuba ube nombono kunye nokusombulula ingxaki yezibalo okanye uzobe i-engile echanekileyo. Ungagqibezela iprojekthi yokwakha esungulwe kwilizwe langaphandle okanye uzobe iplani yeprojekthi yokuphucula ikhaya. Ngokuyiqonda kakuhle indlela irula esebenza ngayo, uya kuba ungathinteki ngokwemathematika.

I-Imperial okanye i-metric?

Umlawuli wakho ulinganisa izinto usebenzisa inkqubo yobukhosi, inkqubo yemetric, okanye zombini - iyunithi enye yobude kwicala ngalinye. Imilinganiselo ye-imperial zii-intshi, kunye nokunyuswa okuncinci okuboniswa ngamaqhezu. Kwi-metric system, i-millimeters kunye ne-centimeter enkulu (ishumi leemilimitha) yimigangatho, kunye nokunyuka okurekhodwa kwiidesimali. Inkqubo yemetric ngumgangatho wehlabathi, kodwa kunokwenzeka ukuba udibane nee-intshi kunye neenyawo e-United States.

Ukulinganisa ngee-intshi

Uninzi lweerula ze-intshi ezisemgangathweni ziyi-intshi ezili-12, okanye unyawo olunye, ubude, kunye ne-intshi nganye yahlulwe yangamacandelo alishumi elinesithandathu. Imigca eyahlula icandelo ngalinye inobude obahlukeneyo kuba imele amaqhezu athile. Imigca emide ichonga i-intshi nganye, isoloko inani elipheleleyo, kwaye imigca yesibini-emide kakhulu yahlulahlulwe kwi-1/2-intshi yamacandelo. Imigca yesithathu emide kakhulu imele imilinganiselo ye-1/4-intshi, ngelixa imigca yesibini emifutshane idibanisa i-intshi yekota ukuya kwi-1/8th-inch increments. Imigca emifutshane ilinganisa amacandelo e-1/16-intshi.

Irula yemetric

Inkqubo yemetric yenye indlela yokulinganisa imigama emifutshane, kunye neerula eziqhelekileyo ezifikelela kwi-30 centimeters ubude. Imigca emifutshane kwirula yesistim yemetric imele eyona yunithi incinci yomlinganiselo, i-millimeter. Zonke iimilimitha ezilishumi zidibanisa ukuya kutsho kwisentimitha enye, ezichazwa yimigca emide kunye namanani apheleleyo. Isentimitha nganye inomgca wobude obuphakathi uwunqunqa kabini ube ziziqingatha, nangona uya kubhala imilinganiselo kwiidesimali kuneziqhezu. Isiqingatha sesentimitha, umzekelo, kufuneka sibhalwe njenge-0.5 centimeters.

Ukuthatha umlinganiselo ochanekileyo

Xa ulinganisa into okanye umgama ngerula, qala ukhangele umgca onguziro. Ngokungafaniyo ne-tape measure, irula inobude obongezelelweyo ekupheleni kwayo, ukuba ingabonakali, inokubonelela ngemilinganiselo engachanekanga. Lungelelanisa inqaku elinguziro nomphetho wento ometayo, uze ufunde ukusuka ekhohlo ukuya ekunene. Umgca ophawula isiphelo somgama orekhodayo bubude bakho. Ukuba ikwisahlulo sesiqingatha phakathi kwamanqaku alithoba kunye neshumi intshi, umlinganiselo wakho yi 9-1/2 intshi. Ukuba yimigca emibini emincinci edlulileyo 13 kwirula yokulinganisa, ixabiso lakho yi-13.2 yeesentimitha.

Uguqulo

Mhlawumbi ufumene iprojekthi yokuphucula ikhaya kwi-intanethi, kodwa imilinganiselo yayo ikwinkqubo yemetric. Ngalo lonke ixesha unokurekhoda ubude obuchanekileyo kwi-metric okanye imilinganiselo yobukhosi, uguqulo kulula ukubalwa usebenzisa iqhezu kunye netshati yokuguqulwa kwedesimali. Uyakwazi ukwenza izibalo ngokwakho, kodwa ukusebenzisa iphepha lokukopela kuyakhawuleza kwaye kuthembekile xa kufuneka ingqalelo yakho kweminye imisebenzi. Iikhalityhuleyitha ezikwi-Intanethi nazo zenza iqhinga.

Abalawuli abaqhelekileyo

Uninzi lwabantu luyakwazi ukudlula ngerula yedesika eqhelekileyo yokulinganisa imigama yemihla ngemihla kunye nokuzoba imigca ethe tye. Kwizinto ezingaphezulu kwee-intshi ezili-12 okanye iisentimitha ezingama-30, iyadi okanye intonga yeemitha ifanelekile ngakumbi. Umlawuli wensimbi unamandla ngakumbi, kwaye ukwakhiwa kwawo okuncinci, okuthe tye kukuvumela ukuba udwebe ngokuchanekileyo imigca. Iirula zeplastiki eziguquguqukayo zezona zilungele ukulinganisa indawo engalinganiyo okanye egobileyo.

Ubugcisa kunye nobunjineli

Ukuseta izikwere sisixhobo esidumileyo kwibhokisi yesixhobo yegcisa okanye yobunjineli, nangona igama lilahlekisa kancinci. Ezi balawuli zibunxantathu kwaye zisikwe embindini, zibonelela ngemiphetho ethe tye. Zikulungele ukwenza imigca ehambelanayo kunye ne-perpendicular kunye nee-angles ezifanelekileyo kunye ne-30- kunye ne-60-degree angles. Iirula ezihambelanayo zizoba imigca eneengile echanekileyo kunye nezithuba. Yongeza i-protractor, kwaye unayo ipakethi efanelekileyo yokuqalisa igcisa.

Esona sipho sokufudumala kwendlu

Isikwere sesantya sisixhobo semisebenzi emininzi esenza isipho esigqibeleleyo sokufudumala. Ngaphandle kokuthatha imilinganiselo eqhelekileyo, ikwanceda ukuba ufumane kwaye uzobe ii-engile ezichanekileyo usebenzisa indawo yepivot kwelinye icala. Omnye umgca wesquare wesantya unomlebe oqinileyo owumisayo ngelixa uthatha imilinganiselo okanye njengoko ukhokela isarha yesetyhula kumgca othe ngqo. Iinotshi kumphetho ongaphakathi zikunceda ukuba ubhale imigca ethe tye kwiplanga kwaye wenze isivuli sebhotile esingaqhelekanga.

Abalawuli abaziingcali kwishishini

Irula yesikali somatshini wentsimbi ilungele oomatshini kunye neengcali zevenkile ezifanayo ezifuna imilinganiselo echanekileyo. Isixhobo sibonisa ukunyuka kwe-intshi ye-1/16 kwelinye icala kunye ne-1/32nd-increments kwelinye. Abalawuli be-hook beza kunye nokubamba ekugqibeleni ukuze bafake ngokuchanekileyo indawo ye-zero ngaphandle kobuninzi obongezelelweyo bomlinganiselo weteyiphu. Iicalipers zilinganisa i-diameter yangaphakathi okanye yangaphandle yeesilinda, imibhobho, kunye nokuvuleka.

Isixhobo esiyimfihlo somchweli

Abachweli banokusebenzisa iteyiphu yokulinganisa emsebenzini, kodwa akuqhelekanga ukubona idizadi ngamaxesha athile okanye irula esongwayo kwindawo yokusebenzela. Ngokuqhelekileyo zenziwe ngamaplanga okanye ngentsimbi, iirula zokugoba ziyakwazi ukwenza ii-angles, ii-angles zokudlulisa, okanye ukuzoba izangqa ze-impromptu. I-T-squares nayo iluncedo kubachweli, abayili bezakhiwo, kunye nezinye iingcali ekuyileni nasekucwangciseni.
