Ica mbere, igikorwa co gukina ni ciza. Irafise ukuntu imeze neza, ishobora gutera ibihimba vy’imiterere bikomeye, nk’umubiri w’ivyuma vy’ivyuma bifise imiterere y’umwobo w’imvi n’ivyuma vy’imvi birabereye cane. Kandi igipimo c’ugugabanuka kwayo ni gito, ivyo bikaba bishobora kugabanya ubushobozi bwo gutera imyobo yo gutera, imivyimba n’izindi nzira.
Ica kabiri ni umutungo mwiza cane wo gufata ibintu. Ishobora gufata neza ukunyiganyiga, nk’umubiri w’igitanda gikozwe mu cuma c’umweru, birashobora kugabanya ukunyiganyiga mu nzira y’akazi, kugira ngo bibe vyiza.
Ica gatatu, ubushobozi bukomeye bwo kwambara. Ivyuma vy’ivyuma vy’ibara ry’agahama birimwo graphite, graphite irafise ingaruka z’amavuta, ishobora gukoreshwa mu gukora impeta ya piston, ingoma y’amafirimi n’ibindi bice bikeneye ubushobozi bwo kwambara.
Ica kane, igikorwa co guca no gukora ni ciza. Kubera ko iyo graphite ibaho bituma icuma c’umweru kigira icuma mu gukora neza, igikoresho co gucapura coroshe guca, kwambara igikoresho ni gito, rero biroroshe cane gukora mu bice bitandukanye .
