For an Oldham coupling used between two shafts, which among the following statements are correct?
I. Torsional load is transferred along shaft axis.
II. A velocity ratio of 1: 2 between shaft is obtained without using gears.
III.Bending load is transferred transverse to shaft axis.
IV. Rotation is transferred along shaft axis.

1. I and III
2. I and IV
3. II and III
4. II and IV

Correct Option: B

The oldham coupling connects parallel shafts having small offset and in this coupling the motion (rotation) and torsion load transfer is along axes of shafts.
