Question 4 As you learned in lectures and QA2, it is important to design systems for the fact that different parts will expand at different rates under heating. Aluminium rivets

used in airplane construction are made slightly larger than the rivet holes and cooled by 'dry ice' (solid carbon dioxide) before being driven. If the diameter of the rivet at -78.00 °C (the temperature of dry ice) is equal to that of the 3.000 mm hole, what should the diameter of the rivet be at 20.00 °C? Assume that the coefficient of linear expansion remains constant at 2.500 x 10^-5 K^-1.
