if a c-shaped metal is heated, will the slit grow bigger or smaller?

Answer 1

If you heat a ‘O’ shaped metal, all the points on the outer circle and all the points in the inner circle move out ward along the radius.

In other words, inner radius and outer radius of the ring increases.

In the case of a ‘C’ shaped metal also, all the points on the outer circle and all the points in the inner circle move out ward along the radius.

Therefore, the gap increases.

Best way to understand this is to use a magnifying lens and view the letter C. we can
see the gap widening.

Answer 2

Just a guess, assuming it was heated evenly the slit would get smaller. The outside of the "C" has a larger diameter then the inside and would have more metal to expand.

Answer 3

First it will get hot. So dont touch it. Second, it will expand = bigger. I know you mean the gap between the two ends, my experience is it gets rather wide. Bud depends on the radius of curve, size of gap and other tings. In theory, the gap ought to close - but long wise is not the only way metals expand and it is hard to measure - unless you plan carefully.

Answer 4

my guess is bigger, since the atoms would be moving faster, and the natural "grain" of the metal would have pressure pushing in on it, wanting it to "uncurl"

Answer 5

it wouldnt do anything but get hot..?

Answer 6

it is deformed.
