Chifukwa chiyani ili ndi hexagonal, osati ina?
Anthu ambiri adzakhala ndi funso lotere, chifukwa chiyani bolt iyenera kupangidwa kukhala mawonekedwe a hexagonal?Ndipo osati ena?Hexagon ndi chinthu chogwirizana pakati pa kutalika kwa mbali ndi ngodya yopindika.
Kwa mabawuti okhala ndi mbali zosamvetseka kutalika, mbali ziwiri za wrench sizifanana.Kuonjezera apo, m'masiku oyambirira, panali ma wrench okha, ndipo mitu yambiri ya wrench inali ngati lipenga, kotero ma wrench sanali oyenera kupanga magetsi.Kuonjezera apo, mbali yokhotakhota ndi yofunikanso kuganizira.Ngati ndi ngodya inayi, wrench iyenera kutembenuzidwa madigiri 90 kuti akonze zomangira, zomwe sizili bwino kuti zikhazikitsidwe pamalo opapatiza;Ngati ndi octagonal kapena decagonal, ngakhale ngodya yokhotakhota imakhala yaying'ono, mphamvu imakhalanso yaying'ono, ndipo ndiyosavuta kuzungulira.
Chifukwa chake, mawonekedwe a hexagon ndiosankha wamba pama bolts.
