Imagine you have a bunch of sticks stacked on top of each other. These sticks are called timber. Shakes are when these timber sticks start to break apart and become separated from each other. This can happen because of things like age, weather, or bugs that eat away at the timber.
When shakes happen, the timber becomes weaker and may not be able to support things that were once on top of it, like a roof or a floor. This can be dangerous, so it’s important to fix the shakes by removing the damaged timber and replacing it with new, stronger pieces.
Think of it like a game of Jenga - if too many of the wooden blocks start to break apart and fall out, the whole tower might come crashing down. Just like we have to replace those blocks in Jenga, we have to fix the shakes in timber to keep things safe and sturdy.
