Iyintoni indlela yokubala yesalathiso seplastiki ye izitena ezikhanyelayo?

Indlela yokubala isalathiso seplastiki yezitena eziphikisayo kukucubungula ubunzima bodaka kwi-sphere kunye nobubanzi obuyi-45mm, uyibeke kwi-plasticizer, kwaye uyicinezele ngobunzima kuze kube yilapho iqala ukubonakala. Isalathiso seplastiki yesitena esichasayo yinqanaba lokuguqulwa kwebhola lodaka phantsi kwesenzo samandla angaphandle, oko kukuthi, imveliso yoxinzelelo kunye noxinzelelo. Ifomula yokubala imi ngolu hlobo lulandelayo:

Isalathiso sePlastiki S=(d－b)G

d——Idayamitha yokuqala yebhola yodaka, cm;

b——Ubude bebhola yodaka emva kokuba icinezelwe ngumxhuzulane, i-cm;

G——Umthwalo xa ibhola yodaka icinezelwe kuze kuvele intanda yokuqala, kg.
