Po'lat arqonni hisoblash. Po‘lat arqonlar hisobiy cho‘zi- luvchi kuch bo‘yicha hisoblanadi:
■^ * ^ma. N ( 10)
bunda: 5 max — arqon tarmog‘idagi maksimal ishchi kuch, N; К — mustahkamlik koeffitsienti bo‘lib, u arqonga ta’sir etadi- gan eng kichik cho‘zuvchi kuchning shu arqondagi eng katta ish kuchiga nisbatini ifodalaydi va Davlat texnika nazorat talabiga binoan arqonning vazifasi hamda mexanizmlarning ish rejimi bo‘yicha 4-jadvaldan qabul qilinadi;
£ ш — arqonga ta’sir etayotgan uzuvchi kuch, uning qiymati DAST 2688-80, DAST 7668-80, DAST 7665-80 bo‘yicha arqon konstruksiyasining xili, uning diametri va materialining mustahkamlik chegarasi bo‘yicha 5, 6, 7-jadvaldan qabul qilinadi.
