Consider that modern machines mostly use short bearings due to the following reasons:

1.   l/d of the most modern bearings is in the range of ¼ to 2.          

2.  NO end leakage of oil from the bearing

3.   Shaft deflection and misalignment do not affect the operation.

4. Can be applied to both hydrodynamic and hydrostatic cases.

         Which of the above are correct?

         (a) 1 and 4                      (b) 2 and 3

         (c) 1 and 3                      (d) 2 and 4
