Chithandizo chimodzi chodziwika bwino ndi chithandizo cha kumapeto chomwe chimapangidwa kuti chitenge mphamvu ya kugwedezeka mwa kupangitsa mutu wa kugwedezeka kutsika kutalika kwa chotchingira choteteza. Malo otsiriza awa amagwira ntchito m'njira ziwiri. Akagundidwa molunjika, mutu wa kugwedezeka umatsika pansi pa chotchingira choteteza, kapena kutulutsa, chotchingira choteteza ndikutumiza chotchingira kutali ndi galimotoyo mpaka mphamvu ya kugwedezeka kwa galimotoyo itatayika ndipo galimotoyo yatsika pang'onopang'ono.
