What is backlash error and why is it caused?

ABacklash is the error in motion that occurs when gears change direction
Correct Answer
BBacklash is the error in reading that occurs due to least count of instrument
CBacklash is the error in reading that occurs due to zero error of instrument
DNone of the above

Solution

Backlash is the error in motion that occurs when gears change direction. It exists because there is always some gap between the trailing face of the driving tooth and the leading face of the tooth behind it on the driven gear, and that gap must be closed before force can be transferred in the new direction.
