K omillar-Misol
Hex Qopqoq Vida 1/2 - 13 sink qoplangan daraja 5
Foydalanish Moment = K x d x F K = .20
d = 0.50 in.
F = (75 foiz ning the dalil loreklama) = 0.75 x 85,000 psi x 0.1419 kv.in = 9045 lbs.
T = (0.20) (0.5 in.) (9045 lbs.) T= 905 in.-lbs. = 75 ft.-lbs.
In the oldingi misolmiltimos, biz hisobga olinadi K = 0.20. Bu hisoblanadi a commyoqilgan K omil uchun rux bilan qoplangan mahkamlagichlar.
We must hozir hayrat nima may bor sodir bo'ldi agar the person mahkamlagichni o'rnatish bor haddan tashqari yog'langan the murvat va into'xtab qoldi u bilan the same torque. In shunday sharoitlar, K mtomchi uchun a value ning 0.10.
Agar T = K x d x F, thuz biz mumkin shuningdek oldini olishmine the oldindan yuklash, F, ichida the same yo'l.
F = T / (K x d)
F = 905 in.-lbs. / (0.10 x 0.50 in.) = 18,100 lbs.
The qiymat olingan uchun bizning oldindan yuklash, 18,100 funt, vould oshib ketish the kuchlanish kuch ning a 1/2 - 13 daraja 5
murvat.Moqayta tha likely the murvat bilan kiriting savol bo'lardi bor muvaffaqiyatsiz. The aynan qarama-qarshimbor shuningdek sodir bo'ldiultng ichida a lower clamp loreklama tha maybe requg'azablangan resultng ichida maydon muvaffaqiyatsizuqayta.
