Izitimela zensimbiUdlale indima ebalulekile ekwakheni ingqalasizinda yezwe, ukuguqula izinto zokuhamba kanye nokunika amandla ukukhula kwezomnotho. Kusukela ezinsukwini zokuqala zokuguqulwa kwezimboni esikhathini sanamuhla, ukuvela kojantshi bensimbi kube yinto evuselelwa ngobuhlakani nobunjiniyela bobunjiniyela.
Umlando wezitimela zensimbi ungalandelelwa emuva ekuqaleni kwekhulu le-19 ngekhulu le-19 lapho isidingo sezinhlelo zokuhamba ezisebenza kahle zivuse ukuthuthukiswa kwezitimela. Ngaphambi kokwethulwa kojantshi bensimbi, ojantshi bepulangwe bavame ukusetshenziswa, kepha babevame ukugqoka nokuklebhula, banciphisa isivinini namandla ezitimela. Ukuqala kojantshi bensimbi kumake ukuthuthuka okubalulekile, njengoba banikela ngokuqina okuphezulu namandla, bavumele ukwanda kwamanethiwekhi ojantshi kanye nokuhamba kwemithwalo esindayo.
Ngesikhathi sokuguqulwa kwezimboni, ukukhiqizwa kwezitimela zensimbi zandelwa intuthuko ebalulekile, ngenxa yezinqubo ezintsha ezinqubweni zokukhiqiza zensimbi. Inqubo ye-Bessemer, yathuthukiswa ngawo-1850s, yaguqula ukukhiqizwa kwensimbi ngokunika amandla ukukhiqizwa kwesisindo sensimbi esezingeni eliphakeme ngentengo ephansi. Lokhu kuhlanekezelwa kwakha indlela yokwamukelwa okwenziwe ngawo ojantshi wezinsimbi, njengoba bebengabizi kakhulu futhi betholakala kumaphrojekthi wokwakha ujantshi.
Ukuqina nokuqina kweojantshiube yithuluzi ekwenzeni lula ukukhula kwezimboni nezentengiselwano. Amandla ojantshi wensimbi ukubekezelela imithwalo esindayo nezimo zezemvelo ezinokhahlo ziye zazenza zibaluleke kakhulu ekuthuthweni kwezimpahla nabagibeli bawela amabanga aphezulu. Ngenxa yalokho, amasistimu wesitimela asephenduke ahlanganiswe emnothweni womhlaba, esebenza njengendlela yokuhweba yezohwebo nezentengiselwano.
Esikhathini sanamuhla, ukuvela kojantshi bensimbi kuyaqhubeka ukwenzeka, kuqhutshwa yintuthuko ku-Material Science and Engineering. Ukuthuthukiswa kwama-alloys ensimbi anamandla kanye namasu okukhiqiza athuthukile athuthukile athuthukise ukusebenza nokuphila isikhathi eside kwemija yensimbi. Lokhu okusha kukwenze kwakhiwa ukwakhiwa kwamanethiwekhi wesitimela aphezulu kanye nokwanda kwengqalasizinda yesitimela ukufeza izimfuno zomhlaba ovela ngokushesha.
Ukubaluleka kweIzitimela zensimbiEngqalasizinda yesimanje ayikwazi ukweqiwa. Bakha umgogodla wezinhlelo zokuhamba, amadolobha axhumanisa amadolobha, izifunda, kanye namazwe, futhi alekelele ukunyakaza kwabantu nezimpahla. Ngaphezu kwalokho, ujantshi wensimbi ufaka isandla emizamweni yokusimama ngokunikeza indlela yokuhamba esebenza kahle yokuhamba, ukunciphisa ukuphuma kwekhabhoni kanye nokunciphisa ukugcwala kwethrafikhi.
Uma ubheka phambili, ikusasa lamajadi ensimbi linikeza isithembiso sentuthuko enkulu kakhulu. Imizamo yocwaningo nentuthuko igxile ekuthuthukiseni ukusebenza kahle kanye nokusimama kwezinhlelo zesitimela, ngokugcizelelwa okujulile ekunciphiseni umthelela wezemvelo nokwenza ngcono ukusebenza okusebenzayo. Ukusuka ekwamukelweni kobuchwepheshe bezitimela ezintsha ekuqalisweni kwezixazululo zengqalasizinda ezihlakaniphile, ukuvela kojantshi bensimbi kulungele ukuqhubeka nokubumba isimo sezokuhamba kanye nezinto zolwazi.
Ekuphetheni, ukuvela kojantshi bensimbi kube wuhambo olumangalisayo, kusukela ekuqaleni kwabo ukuthobeka ngesikhathi sokuvuselelwa kwezimboni kuya endimeni yabo yanamuhla kwingqalasizinda yanamuhla kwingqalasizinda yanamuhla kwingqalasizinda yanamuhla kwingqalasizinda yanamuhla kwingqalasizinda yanamuhla. NjengoTestament kuya ekuqalweni komuntu nenqubekela phambili, ujantshi wensimbi uguqule indlela esixhuma ngayo nokuhamba ngayo, ibeka amathrekhi ngekusasa lokuhamba okuzinzile nokusebenza kahle.
