Answer
Ingaruka zipakurura (cyangwa imbaraga zipakurura) ni bibi cyane kubigumana impeta kuruta gupakira ibintu. Iyo misa ikubise igice cyagumishijwe, ingufu za kinetic $ E_k = \ frac {1} {2} mv ^ 2 $ igomba kwinjizwa nimpeta na groove. Ibi birema umutwaro wigihe gito $ P_ {impinga} $ ishobora kuba inshuro nyinshi kurenza uburemere buhagaze. Umutekano $ K $ ugomba kongerwa kuva kuri 3 (static static) ukagera kuri 5 cyangwa 10 kubisabwa. Kunanirwa gukosorwa akenshi bisa nk '' deformasiyo ya groove 'kubera ko imbaraga zo hejuru zirenze imbaraga zumusaruro wamazu mugice cyamasegonda, bigatuma impeta irya kandi igasohoka. Ba injeniyeri bagomba gukoresha impeta zuruhererekane 'Heavy Duty' (umubyimba $ T $ hamwe n $ $ d $) kandi bakagenzura igishushanyo bakoresheje theorem-momentum theorem ($ F \ cdot Δt = m \ cdot Δv $).
