Question 8967: By how much should a mechanist decrease the lenght of a rod that is 4.78 cm long if the lenght must be 4.5+_ 0.02 cm? Answer by DWL(56) (Show Source):
You can put this solution on YOUR website! the maximum the rod can be in length is 4.50 + .02 = 4.52.
the shortest the rod can be in length is 4.48
the machinist must reduce it by .08 cm.
least amount to reduce is 4.78 - 4.52 = .26 cm
Maximum amount to reduce is 4.78 - 4.48 = .30 cm
Answer is the machinist should reduce the rod between .26 cm and .30 cm. to make it in tolerance of +- .02 cm
