As an object gets heated it expands. If the objet were spherical with a hollow cavity, when the sphere expands the cavity also expands creating a larger cavity, right? Suppose the object were a 2 ft Dia. sphere with a ½ ft Dia. hole in the center made of a hard carbon steel that begins to expands at 9000o F. And a second object being a ½ ft Dia. sphere with a 1in Dia. hole in the center made of a hard steel that begins to expands at 1000o F. If the ½ ft dia sphere where to be place inside the 2 ft dia sphere and the latter where heated to 2000o F as the ½ ft dia sphere tries to expand, but can’t due to the in-expansion of the 2 ft dia, what happens to the 1 in cavity of the ½ ft dia sphere? Does it still get bigger, or does it begin to close? If it does close, how much pressure is exerted in the center of that sphere?
Re: Can an object expand if it where placed inside an in-expandible object?
