Driveshaft speed variation is being discussed. Technician A says the speed variations at the transmission yoke end of the driveshaft are canceled out by the speed variations at the pinion flange end. Technician B says the operating angles at each end must be equal for the speed variations to cancel each other out. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both technicians are correct. Technician A is correct in stating that the speed variations at one end of the driveshaft are meant to be canceled out by the variations at the other end, which is a principle of driveshaft operation. Technician B is correct in stating that for these variations to cancel each other out effectively, the operating angles at each end of the driveshaft must be equal. This is essential for smooth operation and to prevent vibrations or wear.
