HCF of 20 and 30 is the largest possible number that divides 20 and 30 exactly without any remainder. The factors of 20 and 30 are 1, 2, 4, 5, 10, 20 and 1, 2, 3, 5, 6, 10, 15, 30 respectively. There are 3 comm
In simple words, the HCF (Highest Common Factor) of two natural numbers x and y is the largest possible number that divides both x and y. Let us understand this HCF definition using two numbers, 18 and 27. The common factors of 18 and 27 are 1, 3, and 9. Among these numbers, 9...
The high cycle fatigue (HCF) tests of modified 9Cr-1Mo dissimilarly welded joint were carried out at different elevated temperatures and the fracture mechanism was systematically revealed. The fatigue strength at 108cycles based onS–Ncurve can be estimated as a half of weld joint's yield ...
