Figure 3 shows a bimetallic strip with a wooden handle, suspended horizontally
using a thin thread.

The strip is heated at the point shown. Explain why the system tips to the right.

Answer:

- On heating, the bimetallic strip bends. This is because the position of
the centre of gravity to shift to the right causing imbalance that makes the
strip to trip to the right
