A uniform circular disc with an off-centre circular hole lies on a smooth horizontal surface. C is the centre of the disc and A is a point on its rim, as shown. What happens as the temperature is increased?
Options:
Answer:
D
Solution:
There is no horizontal external force, so the material centre of mass remains fixed.
On uniform expansion, the geometric centre C shifts left and the rim point A moves right.
Therefore option D is correct.
