Ifomula yokubala umthwalo wetsheyini

Ifomula yokubala umthwalo wetsheyini yile ilandelayo: Ifomula yokubala ubunzima bemitha yetsheyini yokuphakamisa? Impendulo: Ifomyula esisiseko linani lamacandelo = ubude obupheleleyo (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (amacandelo) Ubunzima becandelo ngalinye = Ithini ifomula yokubala amandla okutsalwa kwetsheyini yentsimbi ejikelezileyo? Amandla okuqhekeza itsheyini Ukubala amandla okuqhekeza itsheyini yerola yepleyiti 1. Uxinzelelo oluncinci lokuqhekeza lwentsimbi ye-40Cr yi-S=980N/mm2, indawo encinci yokunqumla ikhonkco letsheyini enye ikwiiyunithi ze-B (mm2), kwaye amandla amancinci okuqhekeza itsheyini akwiiyunithi ze-F (N). Ifomyula F=S×B3. Ukubala itsheyini enobukhulu obuyi-10 kunye nepitch 80: B=15*10*2+12. 5*10*2=550mm2F=980*550=539000N Ukubalwa kwetsheyini enobukhulu obuyi-16 kunye nepitch 80: B=15*16*2+12 .5*16*2=880mm2F=980*880=862400N Ukubalwa kwetsheyini enobukhulu obuyi-16 kunye nepitch 120: B=23. 5*16*2+22. 5*16*2=1472mm2F=980*1472=1442560N
