SCREENSHOT OF FIGURE ATTACHED!

A component for a lathe slideway was checked for straightness by means of an autocollimator and a reflector carriage whose base length is approximately 100 mm.The instruments were arranged as depicted in Figure 1. The reading at each position, starting at end A, was recorded and the reflector carriage was moved along the component in increments equal to the base length after each reading was taken.i) The autocollimator readings obtained by this procedure are given on Worksheet 1. Describe the methodology for obtaining these readings.

ii) Complete the table on Worksheet 1 and plot the graph of deviation from the straight line joining the end points, A and B.

iii) Determine the maximum deviation from the straight line joining these end points, and the maximum cumulative error.
iii) If the machine tool specification on the longitudinal level is equal to 0.018 mm/m, comment on how the results from the autocollimator will have on the suitability of the machine tool.https://www.physicsforums.com/attachments/274451

Welcome to PhysicsForums.

It looks like you still need to fill in the table and show your calculations. Can you do that so we can check your work? Thanks.

I need help on how to go about it. Please explain me a bit, I'll do it and then you can check.

That looks to me like a partly-cropped snapshot of something pre-printed ##-## can you please, as @berkeman advised, provide the table that you showed in post #1, but with the empty cells filled in, and with model or sample expressions for the basis for how a result in a cell of a given type was obtained. Forum rules require that we see a reasonable attempt from you at your own solution, before we can say much about our specfic ideas about how we would get to a correct solution.
