Waa maxay qaabka xisaabinta ee dhererka rivet ee dhabta ah?

L= δ+ 1.4 × d

d: Dhexroorka xuubka, δ：: dhumucdiisuna tahay

● Dhererka buuxa ee usha rivet madaxa semi-wareega ah = 1.65 ~ 1.7d + L + 10% wadarta dhumucda saxanka.
● Dhererka buuxa ee usha rivet madaxa nus-countersunk = 1.1d + L + 10% wadarta dhumucda saxanka.
● Dhererka buuxa ee usha rivet-ka countersunk = 08d + L + 10% wadarta dhumucda saxanka.

d = dhexroorka qulqulka

L = wadarta dhumucda saxanka

d.L waa mm
