Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Whakawhiti: Whakaarohia te hoahoa kaha ki te taha matau, i reira kua tino nui te whakaheke. Kua māmā ake te tātaritanga mā te whakaaro ki te ātaahua i tētahi taha anake o te maunga. Ko te plumb-bob o te papatipu m kei te tawhiti d mai i te P, te pokapū papatipu o te maunga o te papatipu MM me te kiato ρM. Ka hurihia i roto i te koki iti θ na tona kukume F ki P me tona taumaha W e aro ana ki te Ao. Ko te tapeke o te W me te F ka puta he taumahatanga T i roto i te aho pendulum. He taumaha a te Ao ME, he radius rE me te kiato ρE.  Pātai: he aha te mea i whakaarohia i roto i te tātari?
