From the experimental values of the coefficient, expanded metal dash fares can be resolved as follows:The expansion coefficient value is final dash of the alloy is linear ((+ 16.0 16.0 16.0 16.1 16.2 + + +))/5 = 16.06.Which have tolerances as compared to standard values as follows (16.06-17 )/17 x 100% = 5.53%.The expansion coefficient value is final dash of brass metal is linear ((+ 17.8 19.7 17.3 17.5 + + + 18.0))/5 = 18.06.Which have tolerances as compared to standard values as follows (18.06- 19 )/19 x 100% = 4.95%.
