For an alignment setup with X=10", L1=20", L2=40", and dial B= +7 with a 6 mil bar sag, what are the vertical moves for shim moves?

In an alignment setup involving shimming, it's essential to understand how the measurements interact to determine the necessary adjustments to achieve proper alignment. In this scenario, shimming calculations often involve taking measurements like dial indicators, distances, and sag to solve for vertical moves.

Given the parameters, the dial reading provided indicates a misalignment which has to be corrected through shimming. The value "X" represents the desired alignment position and "L1" and "L2" represent distances from the reference points to make calculations for shimming. The sag introduces a vertical component that influences how much each side needs to be shimmed.

The provided numbers suggest a need to consider not only the direct value of the misalignment indicated by the dial but also any impact from the sag. The shimming calculations will dictate how much each side needs to go up or down to achieve the alignment goal.

The values of the vertical moves, specifically "S1" and "S2," represent how much to raise or lower each side respectively. The correct values will consider the misalignment values along with any adjustments from sag to target that zero alignment position.

In this case, the selected answer shows that "S1" will require a significant upward adjustment (indicated by a positive number
