Answer
Igice gihoraho kibaho mugihe imihangayiko yimbere mumasoko yumuraba irenze imbaraga zumusaruro ($ \ sigma_y $) yibikoresho, bigatera ihinduka rya plastike. Ibi bikunze kugaragara mugihe uburebure bwubusa bwisoko ($ H_ {kubuntu} $) ari bugufi cyane nyuma yo kwikuramo bwa mbere cyangwa nyuma yigihe cya serivisi. Imihangayiko ntarengwa mumasoko yumurongo iboneka kuri ID cyangwa OD yimpinga. Niba impungenge zibarwa $ \ sigma = \ frac {3 \ pi P D} {4 N ^ 2 b t ^ 2} $ irenze umusaruro ushimishije wibikoresho (urugero, $ 210 ksi $ kuri 17-7PH CH900), isoko ntizasubira muburebure bwambere. Ba injeniyeri bakoresha ibikorwa bya 'preset' - guhuza amasoko kugirango bikomere mugihe cyo gukora - kugirango bitere impungenge zisigara kandi bigabanye gushiraho mugihe cyo gukora. Niba isoko idashoboye mu murima, kugabanuka kwa $ H_ {kubuntu} $ nicyo kintu cyambere cyerekana guhangayika.
