Mashiinadu way kala duwan yihiin waxaana loo kala saari karaa dhawr siyaabood, sida: shaqo ahaan (mashiinada korantada, mishiinada qalabka wax lagu qabto, mishiinada burburinta, iwm.); warshadaha (mashiinada beeraha, mashiinada macdanta, mashiinada dhar, iwm); iyo mabda'a shaqada (mashiinada kulaylka, mashiinka dareeraha, mishiinnada bionic, iwm.).
Intaa waxaa dheer, mishiinadu waxay maraan dhowr marxaladood oo leh hawlo kala duwan inta lagu jiro cilmi baarista, horumarinta, naqshadeynta, wax soo saarka, iyo codsiga. Iyada oo ku saleysan heerarkan kala duwan, injineernimada farsamada waxaa loo sii kala qaybin karaa dhowr nidaamyo hoose oo isku xiran iyo kuwo dhameystiran, sida cilmi baarista farsamada, naqshadeynta makaanikada, farsamada farsamada, codsiga iyo dayactirka.
Xeer hoosaadkan kala duwan -, ee loo kala saaray dhinacyo kala duwan, is dhex gal iyo is dulsaar, taasoo u horseedi karta boqolaal hoosaad{1}} anshax-marineed gudaha injineerinka farsamada. Tusaale ahaan, mishiinada korantada, ee loo kala saaray shaqada, waxay leedahay xidhiidho isku dhafan oo isku dhafan oo hoosaadyo kale ah- anshaxa sida mishiinka kulaylka, mishiinada dareeraha ah, mishiinada marawaxadaha, mishiinada isdhaafsiga, mishiinada tamarta uumiga, dhirta tamarta nukliyeerka, matoorada gubashada gudaha, iyo gaaska marawaxadaha, iyo sidoo kale sub-mashiinada gaaska,iyo sidoo kale sub- qalabyada tamarta dhexe, warshadaha korontada iyo injineernimada baabuurta. Marawaxadaha uumiga badda waa mashiinada korantada, iyo sidoo kale mishiinada kulaylka, mishiinada dareeraha, iyo mishiinada marawaxadaha. Waxay ka tirsan yihiin dhirta tamarta badda, dhirta tamarta uumiga, waxayna sidoo kale ka tirsan yihiin dhirta tamarta nukliyeerka, iwm.
