Match list I with list II :
| List I | List II |
|---|---|
| a. Unwin's formulae | I. Bearing |
| b. Wahl factor | II. Rivets |
| c. Reynold's equation | III. Gears |
| d. Lewis form factor | IV. Springs |
Answer: D
The correct matching is a-II, b-IV, c-I, d-III.
- Unwin's formula, \(d = 6\sqrt{t}\), gives the rivet diameter from the plate thickness: rivets.
- Wahl's factor corrects the shear stress in a helical spring for curvature and direct shear: springs.
- Reynolds' equation gives the pressure in the oil film of a hydrodynamic bearing: bearings.
- Lewis form factor enters the beam strength of a gear tooth: gears.
Only one option has all four pairs. Options pairing Unwin's formula with bearings, or Wahl factor with gears, are wrong at the first pair.
