Question 8967
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
