DIY Pulley for the loungeroom stairs – Go Science Girls

We’ve been wanting to make a pulley for a while now. I’m not quite sure when exactly the fascination started, but it’s been going for a few months at least. Every time my daughter Jewel asked if we could make one, I couldn’t help but think “Yes, we should to get onto that. We’ll need to look up what to do, and make a trip to the hardware store to gather some supplies, including one of those fancy pulley wheel thingies. But right now we have abc and xyz going on.

To be honest, I’d turned it into something that felt a bit daunting. I’m not necessarily afraid of daunting. But then I realised… it really doesn’t have to be that complicated. I realised that we don’t have to make the world’s best pulley on our first attempt. So anyway, that’s the back story behind our pulley design. And, wouldn’t you know, it actually works!

Wheel and axle Wheel and axle are those simple machines which consist of two co-axial cylinders of different diameters and are mounted on an axle.

Types of Simple Machine

Usually the effort is applied to the big cylinder and the load is overcome by the small cylinder. These machines help us by multiplying force. String roller, madani, spanner, etc are some examples of it. In wheel and axle, we have: η = Inclined plane Slanted surface is called inclined plane. In inclined plane, we have: Screw A screw is defined as a simple machine having thread along its cylindrical surface. In screw, we have: Wedge The simple machine which is made up of two incline planes is called wedge.

It consists of a rigid bar which is free to turn about a fixed point called fulcrum. The weight to be lifted is the load and the force applied to the bar is called effort. The distance of the load from the fulcrum is called the load arm and the distance of effort from the fulcrum is called the effort arm. There are three types of lever depending upon the position of the load, effort, and fulcrum. These are First class lever Second class lever Third class lever First class lever A first class lever is one in which the fulcrum lies anywhere between the effort and load.

Second class lever A second-class lever is one in which the load is between the effort and fulcrum. Examples: Wheelbarrow, nutcracker, bottle opener, oar of a rowboat, etc. Third class lever A third class lever is one in which the effort is between the load and the fulcrum Examples: shovel, sugar tongs, finger nut cutter, tweezers, human forearm, fork, fishing rod, etc.
