Understanding The Ferrule Effect (3)
A ferrule is a ring of metal that encircles the end of a wooden pole, to stop it splitting.
This ferrule has been put on the end of a snooker cue.
What would happen if you hammered a nail into the end of the cue? Would the wood split?
There are many questions in the Dentaljuce pages for you to think about. This is to break up the page so you can maintain your focus and concentration, rather than viewing large blocks of text.
You do not have to fill in any questions, quizzes or MCQs to prove you have spent the time doing CPD, as the time recorder has all the details. The time you spend learning on the Dentaljuce site is the basis for your CPD certificates.
I understand. Do not show this message again.
If there was no ferrule, would the wood split if a nail was hammered into it?
