							(40.148-40.125)=coefficint of linear expantion*40.125*(45-20)
(0.023)/(40.125*25)=coefficint of linear expantion
coefficint of linear expantion=0.000022928
therefore coefficint of linear expantion=0.000022928

							given that  
                Initial length(L1)=40.125
                Final length (L2)=40.148
                                      (t1)=20
                                       t2=45
we know that coefficient of linear expansion = (L2-L1)/L1*(t2-t1)
                                                                               = (40.148-40.125)/40.125*(25)
                                                                               = (0.023)/1003.125
                                                                               =2.29*10^-5

							given 
Initial length (l1)    =  40.125
final length (l2)     =    40.148
temp (t1)                =20
temp  (t2)               =45
we had know that
