Bearings rolair spherical airson mèinnean agus muilnean ball saimeant: ag adhartachadh èifeachd agus fad-beatha
Teagasg
An diofar eadar muilnean ball saimeant agus muilnean ball ceirmeag:
Tha muilnean ball saimeant agus muilnean ball ceirmeag nan uidheamachd cudromach a thathas a’ cleachdadh gu farsaing ann an gnìomhachasan leithid mèinnearachd, togail agus innleadaireachd cheimigeach. Ach, tha eadar-dhealachaidhean mòra ann am prionnsapalan obrach agus iomchaidheachd an dà sheòrsa muilnean ball seo.
An toiseach, is e seòrsa de uidheamachd a th ’ann am muileann ball saimeant a thathas a’ cleachdadh sa mhòr-chuid ann an cinneasachadh saimeant, a dh ’fhaodas stuthan amh saimeant a bhleith gu pùdar mìn, a’ toirt orra sùbailteachd agus neart nas fheàrr. An coimeas ri sin, thathas a’ cleachdadh muilnean ball ceirmeag sa mhòr-chuid airson gràinean ceirmeag a bhleith, leis gu bheil cruas mìrean ceirmeag nas àirde na mìrean mèinnearach àbhaisteach agus tha an sgrìobach a tha a dhìth cuideachd nas duilghe.
San dàrna h-àite, an taca ri muilnean ball saimeant, tha èifeachdas cleachdaidh sgrìobach nas àirde aig muilnean ball ceirmeag agus builean bleith nas fheàrr. Tha seo air sgàth gu bheil cruas àrd agus neart teannachaidh aig stuthan ceirmeag, a dh’ fhaodas seasamh nas fheàrr air buaidh agus caitheamh sgrìoban, agus mar sin a’ cumail suas seasmhachd agus cumadh nan clachan bleith aca.
Mu dheireadh, tha muilnean ball ceirmeag freagarrach airson stuthan a bhleith le cruas nas àirde, ach tha na cosgaisean obrachaidh aca nas àirde oir tha feum aca air sgrìoban ceirmeag daor. Tha am muileann ball saimeant freagarrach airson stuthan àbhaisteach leithid saimeant ullachadh, agus tha a chosgais obrachaidh gu math ìosal.
Ann an geàrr-chunntas, ged a bhuineas an dà chuid muilnean ball saimeant agus muilnean ball ceirmeag don roinn de mhuilnean ball, tha eadar-dhealachaidhean mòra ann an raointean tagraidh agus prionnsapalan obrach, agus feumar diofar uidheamachd a thaghadh a rèir fìor fheumalachdan. Ma dh'fheumas an neach-ceannach stuthan a bhleith le cruas nas àirde, faodaidh iad muileann ball ceirmeag a thaghadh. Ma dh'fheumas an neach-ceannach stuthan àbhaisteach ullachadh, faodaidh iad muileann ball saimeant a thaghadh.
