Ol masin i gat kain kain na ol i ken brukim long planti kain rot, olsem: long wok bilong ol (pawa masin, masin bilong lukautim ol samting, masin bilong brukim ol samting, na ol narapela samting); long indastri (ol masin bilong egrikalsa, ol masin bilong maining, ol masin bilong wokim klos, na ol narapela samting); na long wok prinsipel (ol masin bilong hat, ol masin bilong wara, ol masin bilong 'bionic', na ol narapela).
Na tu, ol masin i save go insait long planti step wantaim ol narapela narapela wok long taim bilong risets, divelopmen, disain, wokim, na yusim. Long ol dispela kain kain step, ol i ken brukim 'mechanical engineering' i go long sampela 'interconnected' na 'complimentary' sabsistem, olsem 'mechanical research', 'mechanical design', 'mechanical manufacturing', na 'mechanical application' na mentenens.
Ol dispela kain kain sab-disiplin, we ol i makim long ol narapela narapela samting, i save bung na bung wantaim, na dispela inap long kamapim planti handet sab-disiplin insait long mekenikel enjiniaring. Olsem, ol pawa masin, we ol i makim long wok bilong ol, i gat ol kompleks rilesensip wantaim ol narapela sab-disiplin olsem ol masin bilong hat, ol masin bilong wara, ol masin bilong tabin, ol masin bilong 'reciprocating', ol masin bilong pawa bilong stim, ol nuklia pawa plent, ol ensin bilong paia insait long pawa, na ol ges tabin, na tu ol sab- disiplin olsem ol sentral pawa ikwipmen, ol pawa plent bilong tren, ol tren tren enjiniaring bilong solwara, na enjiniaring bilong ol kar. Ol 'marine steam turbine' em ol masin bilong pawa, na tu ol masin bilong hat, masin bilong wara, na masin bilong tabin. Ol i bilong ol pawa plent bilong solwara, ol pawa plent bilong stim, na tu ol i bilong ol pawa plent bilong nuklia, na ol narapela samting.
