Jadwalka 40 tuubooyinka birta kaarboon waxaa loo kala saaray iyadoo lagu saleynayo arrimo isku dhafan oo ay ku jiraan saamiga dhexroor-ilaa- gidaarka dhumucdiisuna, xoogga alaabta, dhexroorka dibadda, dhumucda derbiga, iyo awoodda cadaadiska.
Magacaabidda jadwalka, sida Jadwalka 40, ayaa ka tarjumaysa isku darka gaarka ah ee arrimahan. Jadwalka 40 tuubooyinka, waxay sida caadiga ah ka muuqdaan dhumuc darbi dhexdhexaad ah, oo muujinaya dheelitirka u dhexeeya xoogga iyo miisaanka. Miisaanka dhuumaha wuu kala duwanaan karaa iyadoo lagu saleynayo arrimo ay ka mid yihiin heerka gaarka ah ee birta kaarboonka ee la isticmaalo, dhexroorka, iyo dhumucda gidaarka.
Ku darista kaarboon birta waxay saameyn kartaa miisaanka, iyadoo kaarboonka ka kooban yahay guud ahaan taaso keenaysa tubooyinka khafiifka ah. Si kastaba ha ahaatee, dhumucda derbiga iyo dhexroorka labaduba waxay sidoo kale door muhiim ah ka ciyaaraan go'aaminta miisaanka.
Jadwalka 40 waxaa loo tixgeliyaa heerka cadaadiska dhexdhexaadka ah, oo ku habboon codsiyada kala duwan halkaasoo qiimeynta cadaadiska dhexdhexaadka ah loo baahan yahay. Haddii aad u baahan tahay macluumaad faahfaahsan ama caawimo ku saabsan Jadwalka 40 tuubooyinka birta kaarboon, waxaad xor u tahay inaad nala soo xidhiidho caawimo dheeraad ah.

Jadwalka 40 kaarboon birta birta ah waa calaamadaynta cabbirka tuubada caadiga ah ee loo isticmaalo warshadaha dhismaha. Waxa ay tilmaamaysaa dhumucda gidaarka tuubada waana qayb ka mid ah nidaamka habaysan ee loo isticmaalo in lagu kala saaro dhumucda gidaarka iyo awooda cadaadiska.
Nidaamka Jadwalka 40:
- "Jadwalka" waxaa loola jeedaa dhumucda gidaarka ee tuubada.
- "Birta kaarboonka" waxay tilmaamaysaa walxaha ka kooban tuubada, taas oo ugu horraysa kaarboon iyo birta.
Jadwalka 40 tuubooyinka birta kaarboon waxaa badanaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan gaadiidka biyaha iyo gaaska, taageerada qaabdhismeedka, iyo ujeedooyinka warshadaha guud. Waxay caan ku yihiin xooggooda, adkeysigooda, iyo wax-qabadkooda, taasoo ka dhigaysa doorasho caan ah mashruucyo badan oo dhismo iyo injineernimo ah.
