Why not make your own simple pulley from a construction set (or just homemade materials like cotton reels and string) and test it for yourself. There's no better way to understand how pulleys work. With a simple two-wheel pulley like this, it's easy to see that you have to pull the...
Simple machines like the pulley give you a mechanical advantage, essentially making you stronger than you are in real life. Physicists quantify the work the system does by calculating mechanical advantage in Newtons, named after Sir Issac Newton, the originator of the laws of motion. It takes 1...
Have your child try to pick up the bucket without the pulley and then with the pulley. Does it make it harder or easier? Keep going with a few rocks at a time. Pin Now try a two-wheel pulley if possible. We used a plant hanger for our set up. You need to put one pulley wheel...
A simple pulley system. If you have ever looked at the end of a crane, or if you have ever used an engine hoist or a come-along, or if you have ever looked at the rigging on a sailboat, then you have seen a block and tackle at work. A block and tackle is an arrangem...
A pulley, as we know is a type of simple machine that changes the direction of the applied force. But what does it look like? How can it be used? And how does it work? We will answer all these questions here, one by one.

When diving into your upper body strength training regimen, incorporating face pulls using a cable pulley machine and rope attachment can significantly boost overall shoulder strength. To truly unlock the benefits, it’s vital to nail the basics starting with grip and stance. ...
How do free energy machines work? Energy: For some work to be done on an object, energy is required. Energy is of many different types throughout the universe. The most common forms of energy we use or feel in our daily life are Kinetic energy, Potential energy, Electrical energy, and ...
How does a Dynamic Pulley System work? A Dynamic Pulley System works by using two or more pulleys connected by a rope or belt. The input force is applied to one end of the rope, creating tension that is transmitted through the pulleys. As the rope passes through each pulley, the force ...
