Kapangidwe: Mphete zamkati ndi zakunja za chigwa chozungulira ndi chozungulira, cholumikizidwa ndi mipira yachitsulo ndi khola. Mapangidwe ozungulira a mphete zonse ziwiri amathandizira kuti mayendedwe azitha kudzigwirizanitsa okha-mbali zonse.
Mfundo Yogwirira Ntchito: Pamene mphamvu zakunja zimagwira ntchito yozungulira, mipira yachitsulo pakati pa mphete zamkati ndi zakunja imanyamula katundu, zomwe zimathandiza kuti mphamvuzo zipirire mphamvu zonse za radial ndi axial. Panthawi imodzimodziyo, zozungulira za mphete zamkati ndi zakunja zimalola kuti chipindacho chidzigwirizane nacho chokha, kuchepetsa kukangana ndi kuvala panthawi yogwira ntchito.
