Answer
Kwagura cyane impeta igumana impeta ibaho mugihe impeta irambuye kurenza urugero rwayo mugihe cyo kuyishyiraho hejuru yumutwe cyangwa muri bore. Ibi bivamo guhindagurika kwa plastike ihoraho, bivuze ko impeta itazasubira kumurambararo wumwimerere 'wiziritse', biganisha kumyuka ikwiye. Umubare ntarengwa wo kwishyiriraho diameter $ D_ {max} $ ugomba kubarwa kuburyo guhangayikishwa na fibre bitarenze imbaraga zumusaruro $ \ sigma_y $. Kwirinda bikubiyemo gukoresha mandel yapanze cyangwa amaboko yo kwishyiriraho, igenzura kwaguka kugera kumupaka runaka. Byongeye kandi, formulaire yo guhangayika mugihe cyo kwaguka ni $ S = \ frac {E \ cdot t \ cdot (D_s - D_i)} {(D_m ^ 2)} $, aho $ D_s $ ni diameter ya shaft na $ D_i $ nubusa impeta imbere ya diameter. Niba $ S> \ sigma_y $, impeta irabangamiwe.
