Answer
Impeta igomba kwagurwa (hanze) cyangwa amasezerano (imbere) kugirango ikureho igiti cyangwa bore. Guhangayikishwa cyane mugihe cyo kwishyiriraho $ \ sigma_ {inst} $ ni $ \ sigma_ {inst} = \ frac {E \ cdot t \ cdot (D_s - D_ {bisobanutse})} {D_m ^ 2} $. Niba $ \ sigma_ {inst} $ irenze imbaraga zumusaruro $ S_y $, impeta izahoraho kandi ntizigera 'yizirika' kumurongo wo hasi. Inganda ninganda ni ukwemeza $ \ sigma_ {inst} <0.8 S_y $. Niba impeta yagutse cyane, diameter yayo yubusa $ D_s $ iriyongera, kandi irashobora kunanirwa gutanga ubushobozi bukenewe bwa centrifugal cyangwa ihagaze neza. Niba porogaramu isaba kwaguka kwinshi, ibikoresho bifite imipaka ihanitse ya elastike cyangwa impeta itandukanye igomba guhitamo.
