To what temperature (in °C) must a cylindrical rod of one metal 10.034 mm in diameter and a plate of second metal having a circular hole 9.984 mm in diameter have to be heated for the rod to just fit into the hole? Assume that the initial temperature is 28°C and that the linear expansion coefficient values for metals one and two are 3.5 x 10-6 (°C)-1 and 17 x 10-6 (°C)-1, respectively.
