A 1.96-kg steel sphere will not fit through a circular hole in a 0.813-kg aluminum plate, becuase the radius of the sphere is 0.10% larger than the radius of the hole. If both the sphere and the plate are kept at the same temperature, how much heat must be put into the two so that the ball just passes through the hole?(adsbygoogle = window.adsbygoogle || []).push({});

Hi, I'm back again with a new question. This question is just about volumetric expansion and linear expansion right? I would use those 2 equations and equate the 2 radii so that the ball can pass through the hole? Am I correct in thinking this?
