Tuke Diameter Nui
He rite tonu te miihini whakapiko putorino ki te piko o te whakarewa pepa.Mēnā he piko parakore, ka piko te ngongo me te diameter o waho o D me te matotoru pakitara o te t i raro i te mahi a te momeniti o waho M, ko te pakitara ngongo o waho o te paparanga kupapa ka pa ki te ahotea σ1, me te ka angiangi te pakitara ngongo;te ngongo o roto o te paparanga kupapa Ko te pakitara e pa ana ki te ahotea σ1, ka matotoru te pakitara paipa.I tua atu, ka huri te ahua whiti mai i te ahua porowhita ki te ahua porotakaroa na te whakakotahitanga o nga mana F1 me F2.Ina he nui rawa te rerekee, ka pakaru te pakitara ngongo o waho me nga kita ki te pakitara ngongo o roto.
