B. Wahl factor
C. Reynold’s equation
D. Lewis form factor
List –II
1. Bearings
2. Rivets
3. Gears
4. Springs
Option (A)
ABCD
1423
Option (B)
ABCD
2314
Option(C)
ABCD
1324
Option(D)
ABCD
2413
Correct Option:
(D)
Question Solution:
A-2, B-4, C-1, D-3
Unwins formula d = 6.1Öt for rivets.
Wahls factor Kw = {(4c-1) / (4c-4)} + {0.615/c} for spring to take in account of stress concentration Reynold equation for journal bearing.
