You may have noticed that, even though our church chairs are independent, and they move around a lot during the week, they always end up in the same places on a Sunday morning. Having a tiled floor, and cunning subtle marks, enables that to happen week after week. Sometimes the chairs are arranged like soldiers, precisely aligned. They probably won’t be on Sunday, because I set them out. If they are, it’s because someone else has pulled them into line.
You may not recognise this wheeled device in the photo. I don’t know what it is called, but it enables you to lift a stack of four chairs effortlessly with one hand and move it to wherever you like in the building. It is a bit of an art, though, getting the stack to land precisely on the marks. Precision is much easier to do if you are physically carrying the stack, though of course that takes more effort.
It’s all to do with the principle of levers. The further you are from the fulcrum, the easier it is to move something – but the less easier to do so with precision.
Likewise, it is much easier to cause havoc with a lever!
Having got this far in this blog, I”m not really sure what to draw from this.
Over to you…
