Foromo ea lipalo tsa ketane

Foromo ea ho bala boima ba ketane ke e latelang: Foromo ea lipalo tsa boima ba chain chain? Karabo: Foromo ea motheo ke palo ea likarolo = bolelele bohle (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (likarolo) Boima ba karolo ka 'ngoe = Ke mokhoa ofe oa ho bala oa matla a ho pota-pota a pota-potileng ketane ea tšepe? Palo ea matla a ho pshatla a ketane ea ketane ea poleiti 1. Khatello e tlase ea ho robeha ha tšepe ea 40Cr ke S=980N/mm2, sebaka se tlase sa sehokelo sa ketane e le 'ngoe se li-unit tsa B (mm2), le matla a fokolang a ketane ke F (N). Foromo F=S×B3.
