Iimveliso

Iibheringi zerola ezijikelezayo zenziwe ngereyingi yangaphakathi eneendlela ezimbini zomdyarho ezithe tyaba kwi-engile kwi-axis yokuthwala, iringi yangaphandle enendlela yomdyarho eqhelekileyo ejikelezayo, iirola ezijikelezayo, iikheji, kwaye kwezinye iindlela, kunye neeringi zesikhokelo zangaphakathi okanye iiringi eziphakathi. Ezi bheringi zinokutywinwa. Uninzi lweebheringi zerola ezijikelezayo ziyilwe ngemigca emibini yeerola, ezivumela ukuba zithwale imithwalo enzima kakhulu yeradial kunye nemithwalo enzima ye-axial. Kukwakho noyilo olunomqolo omnye weerola, ezifanelekileyo kwimithwalo ephantsi yeradial kwaye phantse akukho mthwalo we-axial.

Iibheringi zomatshini wephepha ziyinxalenye yomatshini wephepha.

Iibheringi zomatshini wephepha, eziziibheringi ezizaliswe sisithambisi esiqinileyo esibonelela ngobonelelo oluqhubekayo lweoyile yokuthambisa ukuze ithambiswe ixesha elide.

Iibheringi ezijikelezayo zilawula uyilo, ingakumbi xa kukhethwa iibheringi ezinkulu neziphakathi.
