Question

In automobiles, Hooke’s joint is used between which of the following?

(a) Clutch and gear box

(b) Gear box and differential

(c) Differential and wheels

(d) Flywheel and clutch

The question was asked in examination.

My doubt stems from Friction and Double Hooke’s Joint in section Friction of Machine Kinematics

Answer 1

The correct option is (b) Gear box and differential

The explanation: The main application of the universal or Hooke’s coupling is found in the transmission from the gear box to the differential or back axle of the automobiles. In such a case, we use two Hooke’s coupling, one at each end of the propeller shaft, connecting the gear box at one end and the differential on the other end.
