Fenomenon (1): Imizigo itandukanye izagaragara muburyo butandukanye bwo kuzunguruka byangiritse bitewe nuburyo bwo gusiga nabi.Iyo umutwaro uri muke kandi hari kunyerera, gukuramo uruhu rwiza.Kuberako aribyinshi kandi bisa nkibyobo mumihanda.Dukoresha ibyobo kugirango tubisobanure.Iyo umutwaro ari munini kandi amavuta yo gusiga amavuta aba mato, nko kwinjira mu mazi, iyo inzira nyabagendwa isizwe munsi yigitutu, ibimera bimeze nkibishishwa bizagaragara.Iyo umutwaro ari mwinshi kandi amavuta ni mabi, hazaba ahantu hashyushye cyane kumuhanda, kandi nyuma yo gukomeza gukora, ibice byambere bizagaragara.Impamvu: - Amavuta mabi kubera: • Gutanga amavuta adahagije • Ubushyuhe bukabije bwo gukora • Kwinjira mumazi bitera guterana amagambo menshi hamwe no guhangayikishwa nibintu hejuru yumuhanda - Rimwe na rimwe hariho uburyo bwo kunyerera: - Ongera amavuta menshi - Koresha Amavuta menshi yubukonje bwinshi kandi EP yapimwe inyongeramusaruro aho bishoboka hose - Gukonjesha amavuta / amavuta - Amavuta yoroshye aho bishoboka - Irinda kwinjira mumazi • Umunaniro kubera kwambara.

Fenomenon (2): Kurugero, harikuzunguruka kubintu bizunguruka byafashwe.inzira.Impamvu: Bitewe no kwanduza amavuta, nko kwinjiza uduce tw’amahanga kubera kunanirwa kashe, ibice bitwara byambarwa ahantu hahurira kandi geometrie yibice irahinduka.Igice cyibisubizo byikirenga byaho nabyo bifitanye isano no guhindura bidakwiye ibyuma bifata imashini.Ingamba zo gukosora: - Guhindura mugihe cyamavuta - Akayunguruzo k'amavuta - Gutezimbere kashe - Gusimbuza igihe kashe yangiritse - Kuvura ubushyuhe budasanzwe bwimpeta nizunguruka • Umunaniro uva kumeneka ryurwego rukomeye.

Fenomenon (3): Ibice bikomye hejuru yubutaka bifite ibice binini byumuhanda ucika.Impamvu: - Gucamo cyangwa gutandukanya urwego rukomye - Umutwaro uremereye cyangwa ubujyakuzimu budahagije bwurwego rukomereye umutwaro watanzwe, urugero kubera imitwaro idashushanyije Umuti: - Hindura ubujyakuzimu bwurwego rukomereye kumiterere yimitwaro - Irinde kurenza urugero kuri kuvanaho Isuzumabumenyi Ryerekana Ibiranga Gukora no Kwangirika Kuzunguruka Uburyo bwo Guhuza 51: Kwambara ahantu hatandukanye birashobora guhindura geometrie yakarere gahuza igice kugeza aho imitwaro irenze urugero itera kunanirwa kunanirwa.
