Answer :
Final answer:
In this method of measuring backlash, the bar attached to the driven shaft needs to account for its flexion or deflection, which can affect the accuracy of the dial indicator readings.
Explanation:
In this method of measuring backlash, a bar is attached to the driven shaft and a dial indicator measures its movement. However, this method needs to account for the flexion or deflection of the bar. The bar may bend or warp slightly when a force is applied, causing the dial indicator readings to be inaccurate.
