Aluminum rivets used in airplane construction are made slightly larger than the rivet holes and cooled by "dry ice" (solid co2) before being driven.
if the diameter of a hole is 4.500 mm, what should be the diameter of a rivet at 23.0 *c, if its diameter is to equal that of the hole when the rivet is cooled to - 78.0 *c, the temperature of dry ice? assume that the expansion coefficient of aluminum is 2.4
Answers: 1
Final temperature, 
Diameter of the hole, 
Expansion coefficient of the Aluminum, 
be 
, such that, 
is the elongation in the diameter of the rivet.
is the change in temperature =
