Answer
Ubuvanganzo $ \ mu $ butangiza ingaruka ya 'hystereze'. Iyo isoko yamenetse (gupakira), umutwaro wapimwe $ P_ {umutwaro} = P_ {theoretical} + F_ {guterana} $. Iyo isoko irekuwe (gupakurura), $ P_ {gupakurura} = P_ {theoretical} - F_ {guterana} $. Imbaraga zo guterana $ F_ {guterana} = \ mu P_ {radial} $ iterwa no kwaguka kwinshi kwamasoko kurugo. Mubikoresho bisobanutse neza, iyi hystereze irashobora kuba $ 5-10 \% $ yumutwaro wose. Kugirango ugabanye ibi, abajenjeri bagaragaza urukuta rwamazu rusizwe neza cyangwa bagashyiraho impuzu za PTFE kumasoko kugirango barebe ko preload ikomeza kuba mubyihanganirwa byateganijwe.
