Nkhani - Kodi Mukudziwa Kumene Njanji Zimagwiritsidwa Ntchito?

Njanji zimagwiritsidwa ntchito makamaka m'machitidwe a sitima ngati njira zoyendera sitima. Zimanyamula kulemera kwa sitima, zimapereka njira yokhazikika, ndikuwonetsetsa kuti sitimayo ikuyenda bwino komanso mosamala. Njanji zachitsulo nthawi zambiri zimapangidwa ndi chitsulo champhamvu kwambiri ndipo zimatha kupirira kupsinjika kwakukulu ndi kugwiritsidwa ntchito kosalekeza, kotero zimakhala ndi gawo lofunikira pakuyenda kwa sitima.

Njanji zachitsulo zimagwiritsidwa ntchito kwambiri m'njira za sitima, kuphatikizapo njanji zothamanga kwambiri, njanji zapakati pa mzinda, sitima zapansi panthaka, njanji zopepuka, sitima zonyamula katundu ndi mitundu ina ya sitima. Kuphatikiza apo, njanji zachitsulo zingagwiritsidwenso ntchito pazochitika zina zapadera, monga njanji zopapatiza m'migodi ndi njanji zapadera m'mafakitale. Ponseponse, njanji ndi gawo lofunikira kwambiri pa kayendetsedwe ka sitima.
