sir, if i keep on taking the 0.5mm , than it crosses the peakpoint, because peakpoint is at P.S.R 4.5 how to get 9 like in the graph
@dr.deepakkumar7039
@dr.deepakkumar7039 2 жыл бұрын
Irrespective of 0.5 mm you can use formula to find point of inflection i.e Imax./2.71 we require Imax

While you were taking the reading, results were something different than the result shown in the final observation table at 12:00. Why??
@dr.deepakkumar7039
@dr.deepakkumar7039 2 жыл бұрын
Dear observations already recorded you can say that these are sample reading and it's not similar that shown on simulator.These are pre recorded in observation table.You have to follow the steps shown on simulator.

Dear Adi 2 is the psr and 6 division of HSR coincide with the PSR it's 6*.01 become .06 where .01 is the lease count of screw gauge so total is 2+.06=2.06 please check video again if any doubt
