How does iron blade in the tools is fixed to the wooden handle explain it

Posted by Miss Mannat 5 years, 3 months ago

CBSE > Class 06 > Science (OLD)

1 answers

Yogita Ingle 5 years, 3 months ago

The iron blade of soil digging tools has a ring in which the wooden handle is fixed. Normally, the ring is slightly smaller in size than the wooden handle. To fix the handle, the ring is heated and it becomes slightly larger in size (expands). Therefore, the handle easily fits into the ring. When the ring cools down, it contracts and fits tightly on to the handle.
