To what temperature (in °c) must a cylindrical rod of one metal 10.001 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 27°c and that the linear expansion coefficient values for metals one and two are 4.3 x 10-6 (°c)-1 and 17 x 10-6 (°c)-1, respectively.
