Correct option is B
A
dial test indicator (DTI) works on the
rack and pinion principle. This mechanism converts
linear motion into rotational motion, allowing precise measurement of small displacements.
Working:
·
Rack and Pinion Mechanism:
· The
plunger or stylus moves in response to surface variations.
· This movement is transferred to a
rack and pinion system, which rotates the dial.
·
Measures Small Deviations:
· Used for
checking alignment, flatness, and surface variations in machining.
