Q.

Which one of the following statements is not correct?

A. Hooke’s joint is used to connect two rotating co-planar, non-intersecting shafts

B. Hooke’s joint is used to connect two rotating co-planar, intersecting shafts

C. Oldham’s coupling is used to connect two parallel rotating shafts

D. Hooke’s joint is used in the steering mechanism for automobiles

Answer & Explanation

Universal joint/Hooke's joint is used to connect two nonparallel and intersecting shafts and misaligned shafts.

Thus correct option is: A.
