Isikali Sokuguqulwa Kwesibali

Isilinganiso sesikali :
Ubude Bangempela
Ubude Besikali
Isiphequluli sakho asisekeli isici sekhanvasi.

Uma ufuna ukwazi isikali factor(isilinganiso) phakathi kobude obubili, zama lokhu,umshini wokubala wesici sesikali, Kusisiza ukubala isilinganiso sesikali kalula.

Lesi isiguquli sobude besikali esiku-inthanethi esibala ubude bangempela nobude besikali ngokwesilinganiso sesikali. isilinganiso sesikali singasethwa uwena, sisekela amayunithi obude ahlukene, okuhlanganisa amayunithi ombuso namayunithi wemethrikhi. Ngomfanekiso obonakalayo kanye nefomula, isenza siqonde kalula inqubo yokubala kanye nomphumela.

Indlela yokusebenzisa lesi siguquli sesikali

  1. Setha isilinganiso sesikali ngokwesidingo sakho, isb 1:10, 1:30, 35:1
  2. Khetha iyunithi yobude bangempela nobude besikali
  3. Ukusebenzisa amayunithi ahlukene kuzoguqula umphumela ngokuzenzakalelayo
  4. Faka inombolo yobude bangempela, ubude besikali buzobalwa ngokuzenzakalelayo.
  5. Faka inombolo yobude besikali, ubude bangempela buzobalwa ngokuzenzakalelayo.

Ungabala kanjani usayizi wesikali

Ukubala i ubude besikali, sebenzisa ubude bangempela phinda isici sesikali saso, bese uhlukanisa isici sesikali sobude besikali, isibonelo
Isilinganiso sesikali 1:12
Ubude bangempela: 240 intshi
Ubude besikali: 240 intshi × 1 ÷ 12 = 20 intshi
Usayizi wesikali segumbi esikalini esingu-1:100
Igumbi lamamitha angu-5.2 ngo-4.8 amamitha, ungakanani usayizi wesikali wepulani yesakhiwo esikalini esingu-1:100?

Okokuqala, singaguqula iyunithi ukusuka kumitha ukuya kusentimitha.
5.2 m = 5.2 × 100 = 520 cm
4.8 m = 4.8 × 100 = 480 cm
Bese, guqula ngokukala
520 cm × 1 ÷ 100 = 5.2 cm
480 cm × 1 ÷ 100 = 4.8 cm
Ngakho kufanele sidwebe ikamelo 5.2 x 4.8 cm
Ukubala i ubude bangempela, sebenzisa ubude besikali phinda isici sesikali saso, bese uhlukanisa isici sesikali sobude bangempela, isibonelo
Isilinganiso sesikali 1:200
Ubude besikali: 5 cm
Ubude bangempela : 5 cm × 200 ÷ 1 = 1000 cm
Ububanzi bangempela bomnyango esikalini esingu-1:50
Ohlelweni lwesakhiwo ububanzi bomnyango wangaphambili buyi-18.6 mm.
futhi isikali sohlelo singu-1:50,
buyini ububanzi bangempela balowo mnyango?

Okokuqala, siguqula iyunithi isuka kumilimitha iye kusentimitha.
18.6 mm = 18.8 ÷ 10 = 1.86 cm
Bese, guqula ngokukala
1.86 cm × 50 ÷ 1 = 93 cm
Ngakho ububanzi bangempela bomnyango buyi-93 cm
