Question

The propeller shaft is normally made by seamless steel tubing method with ............... welded to both ends of the shaft.

• A. extra weight
• B. universal joint yokes
• C. external splines
• D. internal splines

Hint:

Tip: Propeller shaft → seamless tube + universal joint yokes for flexibility!

Answer 1

The Correct Option is B

A propeller shaft is used to transmit torque from the gearbox to the differential in vehicles.
It is usually made from seamless steel tubing for strength and balance.
At both ends of the propeller shaft, universal joint yokes are welded.
These yokes connect the shaft to the gearbox at one end and the differential at the other, allowing angular movement and flexibility.
This arrangement accommodates changes in alignment due to suspension movements.
Splines are used inside slip joints for length adjustments, but the ends have universal joint yokes for articulation.
Therefore, the correct answer is universal joint yokes.
