Statement I: Hooke’s joint connects two non-parallel non-intersecting shafts to transmit motion with a constant velocity ratio. Statement II: Hooke’s joint connects two shafts the axes of which do not remain in alignment while in motion.

Statement I: Hooke’s joint connects two non-parallel non-intersecting shafts to transmit motion with a constant velocity ratio. Statement II: Hooke’s joint connects two shafts the axes of which do not remain in alignment while in motion. Correct Answer Statement I) is false but Statement II) is true

A Hook’s joint, commonly known as a universal joint is used to connect two non-parallel and intersecting shafts. It is also used for shafts with angular misalignment. A common application of this joint is in an automobile where it is used to transmit power from the gear box (of the engine) to the real axle.

Since hook's joint connect two intersecting shafts therefore the statement 1 is not correct and it can be used for the shafts which have some angular misalignments.
