Udweba kanjani umbuthano uma engenayo ikhampasi

Izifundo geometry nemigwalo ngokuvamile kudingeka baphathe ikhampasi kanye nekudvweba amathuluzi stencil. Kodwa indlela ukudweba indilinga, uma kungekho amathuluzi akhethekile ususondele? Iza ukusiza amadivayisi savvy futhi ngokurhaba!

A umbuthano ephelele ngesandla

Lokhu kuzodinga ephepheni, ipeni lomsizi noma kanzima aphakathi nendawo kanye isandla esithambile. Ngokusho indlela esetshenziswa cishe bonke abaculi uma kudingeka ukuze isithombe umbuthano ephelele.

1. Dweba indilinga encane (emehlweni kwezilwane, imininingwane yezakhiwo): iphepha ibekwe phezu flat, ipensela kufanele ibe sesandleni njengoba zibhalwe evamile. Abeke isandla sakhe phezu ishidi ukuze lihlale pad ngomunwe kancane. Kulokhu, ukwanelisa isimo ukuthi kubalulekile ukuba ucindezele ishidi ukuze ngesikhathi esifanayo ngokuqinile nabo etafuleni futhi kungenziwa rotated emhlabeni eksisi, okungukuthi, pinky. Isandla yesibili uzungeza iphepha kumbuthano ngaphandle ezihambayo esandleni ngepeniseli. Phakathi kuphenduka, lo wepeni kumele uthinte iphepha, kulandele Ukujikeleza liyakushunyayelwa etholwe ngisho indilinga lencane.

2. Indlela ukudweba umbuthano ububanzi 50 mm? Badinga amathuluzi efanayo, kodwa ipensela phambili kufanele kube soft. Ngokungafani indlela odlule siqukethe ekubekeni inkomba umunwe kancane, kulesi simo-ke kuyadingeka ukugoba futhi ucindezele entendeni. Futhi sithembele umunwe kancane, kodwa hhayi ngokucindezela kanzima ipensela, vula ikhasi bese udweba indilinga.

3. Udweba kanjani indilinga esiphelele ubukhulu esikhulu? I-algorithm lamahubo lilingana, kodwa manje usekela umunwe kancane ukushintsha ithambo bulging esihlakaleni. Uma kuwukuthi ungakhululekile, ungathembela entendeni leaf.

Inselele enkulu kunazo zonke izindlela ezichazwe - yikhono ukuhambisa ingalo yakhe ngepeniseli. Ngemva 2-3 ukuqeqeshwa bese ukhetha elikhulu ijubane ukujikeleza ishidi, lezi zindlela kungaba ngakho elula njengoba ukudweba ikhampasi mbuthano.

Ukudweba nge protractor

Maningi awasona offset lokukhohlwa, ikakhulukazi uma kukhona eziningi ikhampasi, kodwa kukhona protractor. Leli thuluzi enemisebenzi ngokuvamile ubuyisela uhla evamile ngenxa compactness yayo.

Algorithm "Udweba kanjani indilinga ephelele nge protractor" siqukethe izinyathelo 5:

• ku ephepheni ukubeka iphuzu - maphakathi umbuthano;
• unamathisele protractor kuleli qophelo isisekelo sayo (ngokoqobo indawo amathuluzi plastic uma kunesikhala);
• umbuthano penciled ingxenye oyindilinga kufanelekile phezu kwangaphakathi noma umbuthano yangaphandle, yakheke njengoba umkhumbi;
• vula protractor 180 degrees, usuphinda kwangaphambili;
• ukususa protractor ngesandla ukuxhuma emigqeni umsizi isikokela.

Ukudweba nge-CD namabhodlela

Le ndlela ubhekwa elula. Kwanele unamathisele idrayivu ephepheni bese ukipilitela ke emhlabeni uma ufuna ububanzi isiyingi esikhulu. Futhi ukuyisebenzisa kalula ziveza umbuthano kancane, eqalaza kumbuthano ngaphakathi emgodini CD. Abotitjhere sebekubeke kuqhathaniswa le ndlela, echaza indlela ukudweba umbuthano nangezinye izinto ususondele.

Ngokwesibonelo, ingilazi abangaba njengoba esikhundleni nekhampasi. Ngenxa yalesi ingilazi bottomed noma engxenyeni engenhla ogibele liphepha ahaqe ke emhlabeni. Bedplate lapho njengoba ingilazi ngokwayo, ngaphakathi kufanele kube omile, ukuze bonakalise isithombe. Izingilazi ungayithola enye by amathini hairspray, isiqedaphunga ukushefa Foam, egijima ipensela lakhe ezinzulwini yabo.

indlela wezingubo

Ukuze womshini isibonelo ingubo yokugqoka, edinga oyindilinga ingxenye, umthungi necebo indlela ukudweba indilinga. Ukuqala sinquma engaba kwesiyingi esizayo. Ngokwesibonelo, lapho izilinganiso okhalweni waphenduka inombolo 600 mm - lena ubude selilonke. Ukuze abale engaba esetshenziswa ifomula esikoleni: obuphelele circumferential ehlukaniswa 2N.

Ngakho, uhla isibonelo ilingana 600 / 3,14 * 2 = 100 mm.

Manje sidinga amabili alinganayo sobude ipensela. Badinga ukuxhumanisa ngentambo ukuze ibanga phakathi nemakhilayoni welulela ntambo zazilingana 100 mm. Omunye ipensela uyokusekela. ipensela Okwesibili ukusithatha ubude lonke wentambo. Bamba ukwesekwa, kumbuthano ukuze ubambe umugqa ipensela yesibili. Into esemqoka - ukugcina iqine ngentambo. Kuyinto ukukhetha ijubane ukujikeleza okuhola nawokwenza iphepha ogibele endaweni evundlile.

Ukusekelwa ungayithola enye by inaliti ipensela zokubhala.
